Firefox 技術支援討論區

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?

My background color is black, even though I have it set to white under "fonts and colors". Text is set to black, and background is set to white. But the background is actually black. I don't know why it is black when it is set to be white. Thanks for any help.

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?

After the last update to version 95.0 all websites such as github.com changed to dark mode. I am using the dark theme but I still don't want to use dark mode on websites. Is there any way to use the dark theme without using dark mode.

Thanks in advance!

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.

Hi all, Firefox has been using quite a bit of RAM lately.

Ok, I had like a dozen tabs open, but I think this might be a little too many Firefox instances (see screenshot; minimize memory usage just run).

I have already tried disablig tab autostart and decreasing the value of processes in about:config but nothing ever changes.

I hope someone will be able to help me out. Thanks :)

Hope someone can help.

When I use full screen for some websites, it darkens after about 2 - 5 seconds and my cursor also becomes harder to move. This only started to happen recently.

It is not my computer settings, I've tested this in Safari and it works normally. This makes videos unwatchable. It is like a dark screen suddenly appears over the video and only comes off if i move the cursor. It happens with netflix and prime but not youtube, udemy.
