Firefox 附加组件和插件(Firefox add-ons and plugins)有问题？他们似乎被最新的更新禁用了？他们(Don)没有按预期工作吗？在本指南中，我们将分享使用附加组件、插件或不需要的软件修复Firefox问题的技巧。(Firefox)我们正在研究以下场景：
- Firefox 中的附加签名
- Flash 插件问题
- 缺少口袋功能
- 假火狐更新
- 无法删除加载项、扩展、工具栏或主题
- 升级显卡驱动
- Firefox 反劫持搜索。
(Firefox)附加组件和插件的Firefox问题
Firefox在过去几年发生了很大变化，每次更新都会添加新功能和安全措施。这可能会导致附加组件和插件出现问题。让我们来看看如何修复它们。
1] Firefox 中的附加签名
从Firefox版本 57 开始，只有使用WebExtensions API(WebExtensions APIs)构建的扩展才能工作。这可以确保所有扩展在到达消费者之前都已经过验证。如果任何扩展程序不遵循Firefox的安全准则，它们将无法工作，即使它们以前可以工作。
虽然您可以强制 Firefox 使用未签名的附加组件和插件，但最好还是寻找经过认证的更新或寻找替代版本。
2] Flash插件问题
Flash 插件在某些网站上被阻止(Flash Plugin is blocked on some websites)
由于众所周知Flash存在安全问题，因此大多数网站甚至Firefox都不会自动运行任何基于Flash的媒体。相反，您会收到通知。当您单击它时，它会使用 Flash 播放器，然后运行它。如果你想自动运行它，你可以这样做。
- 转到菜单 > 附加组件 > 插件。
- 找到 Shockwave Flash(Locate Shockwave Flash)。默认选项是要求(Ask)激活。
- 要进行更改，请单击首选项，然后取消选中“阻止(Block)危险和侵入性Flash ”框。
虽然最好在每个站点上启用它，但如果您的工作需要它，那么您可以随时启用它。
Flash 插件已崩溃(Flash Plugin has crashed)
发生这种情况时，首先确保插件已更新。您可以转到插件(Plugins)部分>单击齿轮图标，然后单击检查更新。其次(Second)，在 Firefox 中禁用硬件加速，然后检查。(disable hardware acceleration)
闪光灯不工作(Flash doesn’t work)
当上述方法都不起作用，并且Flash内容没有用时，是时候检查Flash播放器，即Shockware Flash是否被禁用。转到Menu > Add-ons > Plugins > Shockwave Flash > Activate。如果已启用，请确保更新图形驱动程序。(update the graphics driver.)
3]缺少口袋集成
(Pocket)Firefox中的(Firefox)袖珍功能允许您保存网站以供以后阅读。如果您无法在收藏夹或书签图标旁边看到 Pocket，请执行以下操作：
- 确保(Make)您已登录Firefox
- 转到 about:config 并输入 pocket
- 双击(Double)extensions.pocket.enabled 为 true。
发布此袖珍(Pocket)图标将立即重新出现在书签图标旁边。
4] 发现假冒的 Firefox 更新
那些必须下载Firefox(Firefox)来更新它的日子已经一去不复返了。安装后，Firefox会自动更新到最新版本。网站或软件提供的任何提示都应视为虚假。如果遇到它们，请不要安装它。
5] 无法删除附加组件、扩展、工具栏或主题
如前所述，如果您无法安装或启用扩展程序，则意味着它们不安全。Firefox对任何与(Firefox)Firefox交互的第三方软件都非常严格。工具栏在扩展下可用。但是，如果您无法删除附加组件、扩展程序或主题，让我们看看我们能做些什么：
在安全模式下删除：(Remove in safe mode:)
- 以安全模式重新启动Firefox。(Firefox in Safe mode.)
- 转到附加组件仪表板。
- 找到它，然后单击删除。
禁用软件安装的扩展(Disable extensions installed by software)
如果任何软件安装了扩展，您将需要使用其配置将其删除。如果没有这样的选项，最好禁用它。转到附加组件(Add-ons)仪表板，找到插件，然后选择禁用它。如果禁用在正常模式下不起作用，请在安全模式下(Safe Mode)或使用组策略禁用它。(using Group Policy.)
手动删除扩展、加载项、插件和工具栏(Manually Remove extensions, add-ons, plugins & toolbars)
这是最后的手段。确保(Make)在最终删除文件时关闭Firefox 。
- 在Firefox(Firefox)的地址栏中输入 about:support并回车。
- 向下滚动(Scroll)，直到找到扩展部分。
- 找到您要手动删除的那个，并记下 ID 值。
- 打开Firefox 配置(Firefox Profile)文件文件夹，然后转到扩展文件夹。这包含每个扩展的XPI 文件，以及安装在(XPI files)Firefox上的主题。
- 找到与您上面提到的 ID 匹配的那个。
- 删除它。
6]升级图形驱动程序
一些扩展使用显卡（硬件加速）和WebGL来加速它们的功能。确保(Make)图形驱动程序是最新的，启用了硬件加速(Hardware Acceleration is enabled)，并且启用了WebGL。这是启用WebGL的方法-
- 在地址栏中，键入about:config，然后接受风险对话框。
- 找到 webgl.disabled
- 双击打开它。
7] Firefox 反(Firefox Anti-hijacking)劫持(Search)搜索
有时，软件、插件和其他软件会劫持Firefox的默认搜索引擎并替换为自己的。虽然Firefox 会警告任何此类更改，但如果您没有注意到，这里是您重新获得控制权的方法
Firefox 自动搜索重置(Firefox Automatic Search Reset)
- 转到首选项并查找搜索(Search)部分
- 将您的默认搜索引擎从下拉列表更改为您喜欢的任何内容。
用户选择重置(User Opt-in Reset)
当Firefox检测到劫持时，您将在窗口中看到搜索重置选项。它会让您接受更改。如果您尚未进行这些更改，请确保拒绝该提议。
最后但并非最不重要的一点是，始终确保向Firefox提交崩溃报告，这从长远来看会有所帮助。
让我们知道这些提示是否有助于您解决有关附加组件、插件或不需要的软件的问题。(Let us know if these tips helped you to fix issues around add-ons, plugins or unwanted software.)
Fix Firefox problems with add-ons, plugins or unwanted software
Having trouble with Firefox add-ons and plugins? They seem to be disabled with the latest update? Don’t they work as expected? In this guide, we will share tips to fix Firefox problems with add-ons, plugins or unwanted software. We are looking at the following scenarios:
- Add-on signing in Firefox
- Flash Plugin issues
- Missing Pocket Feature
- Fake Firefox Update
- Cannot remove add-on, extension, toolbars or theme
- Upgrade Graphics Driver
- Firefox Anti-hijacking for Search.
Firefox problems with add-ons & plugins
Firefox has changed a lot in the past few years, and with every update, new features & security measures are added. This may lead to issues with the add-ons and plugins. Let’s take a look at how they can be fixed.
1] Add-on signing in Firefox
Starting in Firefox version 57, only extensions built using WebExtensions APIs will work. This makes sure that all extensions have been verified before it reaches the consumers. If any extension doesn’t follow security guidelines of Firefox, they will not work, even if they used to work earlier.
While you can force Firefox to use unsigned add-ons and plugins, its best recommended to either find a certified update or look for an alternate version.
2] Flash Plugin Issues
Flash Plugin is blocked on some websites
Since Flash is known to have security issues, most of the websites and even Firefox don’t run any Flash-based media automatically. Instead, you get a notification. When you click on it, it uses the flash player and then runs it. If you want to run it automatically, you can do so.
- Go to Menu > Add-ons > Plugins.
- Locate Shockwave Flash. The default option is Ask to activate.
- To change, click on preferences and then uncheck the box which says “Block dangerous and intrusive Flash.”
While it is best to enable it on a per-site basis, but if your work demands it, then you can always enable it.
Flash Plugin has crashed
When this happens, first make sure that the plugin is updated. You can go to Plugins section > click on cog icon, and click on check for update. Second, disable hardware acceleration in Firefox, and check back.
Flash doesn’t work
When the above methods don’t work, and Flash content is of no use, its time to check if the flash player, i.e., Shockware Flash is disabled. Go to Menu > Add-ons > Plugins > Shockwave Flash > Activate. If it’s enabled, make sure to update the graphics driver.
3] Missing Pocket Integration
Pocket feature in Firefox allows you to save websites to read later. If you are unable to see Pocket right next to favorites or bookmark icon, do the following:
- Make sure you are signed into Firefox
- Go to about:config and type pocket
- Double click on extensions.pocket.enabled to true.
Post this Pocket icon will reappear next to bookmarks icon instantly.
4] Spot fake Firefox update
Gone are those days when you had to download Firefox to update it. Once installed, Firefox will automatically update itself to the latest version. Any prompt offered by websites or software should be considered as fake. If you encounter them, do not install it.
5] Cannot remove add-on, extension, toolbars or theme
As discussed earlier, if you are not able to install or enable an extension, it means they are not safe. Firefox is very strict with any third party software that interacts with Firefox. Toolbars are available under Extensions. However, if you are not able to remove an add-on, extension or theme, let’s see what we can do about it:
Remove in safe mode:
Disable extensions installed by software
If any software has installed an extension, you will need to either remove it using its configuration. If there is no such option, it is best to disable it. Go to Add-ons dashboard, locate the plugin, and choose to disable it. If disable doesn’t work in normal mode, disable it in Safe Mode or using Group Policy.
Manually Remove extensions, add-ons, plugins & toolbars
This is the last resort. Make sure your Firefox is closed when finally deleting the files.
- Type about:support in the address bar of Firefox and hit enter.
- Scroll down till you find Extensions section.
- Locate the one you want to manually remove, and note down ID value.
- Open the Firefox Profile folder, and go to the extensions folder. This contains XPI files for each extension, and the theme installed on Firefox.
- Find the one which matches with the ID you noted above.
- Delete it.
6] Upgrade Graphics Driver
Some extensions use graphics card (hardware acceleration) and WebGL to speed up their functions. Make sure graphics drivers are up to date, Hardware Acceleration is enabled, and WebGL is enabled. Here is how to enable WebGL-
- In the address bar, type about:config, and accept the risk dialog box.
- Find webgl.disabled
- Double click to turn it on.
7] Firefox Anti-hijacking for Search
Sometimes software, add-ons, and others hijack the default search engine of Firefox and replace with their own. While Firefox warns about any such change, in case you did not notice, here is how you gain back the control
Firefox Automatic Search Reset
- Go to Preferences and look for Search section
- Change your default search engine from the dropdown to whatever you prefer.
User Opt-in Reset
When Firefox detects a hijack, you will see a search reset option in the window. It will offer you to accept the change. If you haven’t made those changes, make sure to reject the offer.
Last but not least, always make sure to submit crash reports to Firefox which helps in long terms.
