Firefox 技術支援討論區

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95

I just updated to 95.0. I use default Firefox home page with the Search bar. The background turned to black with this update. The background has also turned to black for some of my bookmarks or sites I go to. Settings, Language and Appearance, Colors, Text is Black and Background is White. I have never changed that. How do I get the background back to White?

Since I upgrade MacOS to Big Sur, a couple basic Firefox functions have stopped working. 1) History is not being saved. I can restore deleted tabs, but there is nothing in the History menu, nor is there any record (for example, in the form of auto-complete) of websites I have visited in the past. 2) My bookmarks file appears to be mostly read-only. Clicking on the star icon to save a new bookmark does nothing. Selecting Bookmarks > Bookmark Current Tab does nothing. In the Manage Bookmarks environment, selecting Add Bookmark from the gear icon brings up a dialog box in which the only content is a Cancel button. In the Manage Bookmarks environment, I can change the Name of a current bookmark but cannot change its URL. If I try, it reverts to the old URL as soon as I click away from it.

The current help page that most closely describes my symptoms is https://support.mozilla.org/en-US/kb/changes-toolbars-and-window-sizes-are-not-saved. I tried both remedies, including refreshing Firefox and deleting xulstore.json, but no change in symptoms.

I've been using Elijah Lopez's Matte Black (Red) theme for months. Recently, I think because I added the ClearURLs extension or some other change, certain websites enter some sort of "dark mode" when accessed.

Websites that do this include Twitter, an independent blog, and Youtube.

The website appears normally with the default light theme enabled. In the second photo, the website appears in the "dark mode" with the black Firefox theme enabled.

I have deleted cookies and cache, reinstalled Firefox, and reinstalled Extensions. I think this problem only occurs with dark themes, and nothing else. The moment I change to dark theme, the problem comes back. It is strange because the dark theme was working just fine for months until recently.

How can I keep the dark theme, preferably the same Elijah Lopez's dark theme, while using websites normally and not in this weird "dark theme" style adaptation?

The documentation says to use F11. F11 was removed from ChromeOS. The Full Screen Button on the keyboard will take Firefox out of full screen, but when you try to use it to put Firefox in Full Screen, the window gets slightly larger, and then goes back to its original size.

Other applications seem to be able to go to full screen using the Full Screen key that are running under Linux. For instance, gvim, thunar, meld, and gnucash all will go into full screen with the Full Screen Key.

When I try to clear cookies and cache etc in Firefox 95.0 on my Mac (OSX 11.6.1), there always remains 811kb, no matter how many times I try and clear it. Deleting the Search history doesn't get rid of it either. Previously, this didn't happen. What's going on please?

After updating Firefox to v95.0 (64 bit) websites start to shown in dark mode.

My windows theme is dark, but i don't want to use same for Firefox. I tried to set ui.systemUsesDarkTheme value as 0 in about:config. But problem still remains.

Is this a bug with new version, or a feature :)

Hi, I have an issue when i goto google.com and try search it always put text in address bar and never in the actual search field. I have tried to change it but can not figure out how. It is very annoying as I have a whole screen for text but it wants to only use the address bar..... Im at the point where I am considering changing browsers due to I can not get use to it and really dislike it.

Since 8 December, 2021, I cannot log into any of my 3 Gmail accounts using Firefox and either Google or Duck Duck Go. I get a message that each is temporarily unavailable - repeatedly. I have no add-ons to Firefox; I cleared the cache. I can access all three accounts using Edge and Bing, bringing up Gmail Accounts and then specifying accounts from within that website. I can't remember when the latest Firefox update happened but it wasn't long ago. I have never had trouble accessing my gmail accounts before now.

I'm working on a reactJs project where we're running an app in an iframe. The app and the project are interconnected. App has an in-page navigation(in same URL) with an anchor tag that allows you to launch a new component in the same tab. It worked and was compatible with all commands prior to the release of the new version of Firefox 95. The click function is not working after the rollout (its not responding in any way). When you use Ctrl + click, a new tab opens with the same URL as the anchor tag with navigated component(and working with target=_blank too). Is this happning beacuse of new security release of RLBox. If this is the case, what other options do I have for resolving the problem?

Hello community,

I have tried many fixes I found online to solve this issue but I have had no luck, this issue even persist into troubleshooting mode. Some sites have white text over a white background and other sites like best buy just have broken html/css, this issue just started happening yesterday for no reason as I have not changed anything of firefox since install, the only additions my browser has is bitwarden and nordvpn add-ons. I have attached pictures as examples. Also if it's any help my system is running Manjaro Qonos 21.2.0

Thank you.

After a Firefox update, Facebook messenger fonts and/or text margins changed and started to look unpleasant to read (too narrow line spacing, the text is crammed vertically and background text fields are smaller). Chromium displays the font as before.

I just downloaded Alfred and now when I try a search from the address bar or the search box on the right, it is defaulting to bing! I have restarted in trouble shooting mode and it is still there. I don't see bing in the drop down of searches in default search engines, in fact the only thing that now shows up there is has the firefox icon and "a browser." I ran malware and it quarantined 17 items. Still have bing. Please help me get rid of this intruder! Thank you

Since a few days, I keep experiencing constant crashes with Firefox. In the most common way, a Tab will crash first, often followed shortly by the whole browser crashing. Crashes occur on, but are not limited to, following pages: • YouTube.com • Reddit.com • Google Account Login • about:preferences • about:crashes • about:support • The very same Support-page I’m writing this on Crashes still occur after: • Rebooting Computer • Clearing of Cache • Starting in Safe Mode (crashes in Safe mode) • Deactivation of hardware acceleration • Refreshing Firefox • Reinstallation of Firefox (Uninstalled with the Uninstall/helper.exe) • Use of Windows Deployment Image Servicing and Management tool (DISM /Online /Cleanup-Image /RestoreHealth)

Crash logs list: • Crash Reason EXCEPTION_BREAKPOINT Crash Address 0x00007ff88082381f • Crash Reason EXCEPTION_ACCESS_VIOLATION_READ Crash Address 0x000001f4465fffe8 I’m kind of out of options. Most support pages are 2 years or older, so I don’t really know if I’m experiencing the same errors as they did. If there’s any more information required, please let me know.
