Firefox 技術支援討論區

It turns out the copied logins-backupjson file i had pasted on my desktop screen was already overwritten by an added or removed login, thus writing over when it did have the saved login removed that i was trying to recover

is there any other way to recover the removed login?

i saw this response by Cor-el for another user with a similar situation

If you still have the signons.sqlite that was used in a previous Firefox version then you can try to restore passwords saved in that file.

Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file that has been used before (the matching key3.db file is still needed). If you still have the signons.sqlite file used in previous Firefox versions then you can try to force Firefox to migrate the passwords saved in that file (you will lose passwords saved in Firefox 32+ versions). You can force Firefox to reimport the passwords from the signons.sqlite file and rebuild the logins.json file with these steps:

   reset the signon.importedFromSqlite pref on the about:config page to the default value via the right-click context menu
   delete the logins.json file in the Firefox profile folder with Firefox closed 

When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.

As from v100.0, Firefox allows users to "set their preferred color schemes for websites".

Ironically, this does not addresses complaints from users, including me, who wish for a consistent Light theme all across Firefox.

Even if "Web site appearance" is set as Light, the following still remain dark:

• Background of main drop-down menu (Containing "Sync and save data", "New tab", "Print", "Settings", etc)
• Background of right-click menu (Containing the refresh icon, "Save page as", "View page source", etc)
• Background of "Please enter primary password" menu
• Background of auto-filled user name and password menus
• Background of elements in a bookmark folder
• Background of Downloads menu
• Background of Print menu
• Background of "Clear all history" menu
• Background of "Find on this page" menu
• Background of "You are about to close X tabs" warning menu
• Colour of title bar for "About Mozilla Firefox" window, when the window is not currently active

Being able to set "browser.theme.toolbar-theme" permanently as 2 would fix all of the above, but users are still (Note: Since v96.0, when this complaint was raised) prevented from doing so. Why?

Amazon 'Look Inside' pop-up does not work with FF as I've configured FF. Iv'e included a screen snip.

I've unchecked block pop-ups but still the 'Look Inside' doesn't work.

I restarted my computer today and downloaded a new version of Firefox. When I started it up again everything was gone... all Tabs, history, and bookmarks. This is a sad loss as I have been organizing my life with Firefox for over 10 years. Is there any going back and getting my firefox restored?

I have a home-built media center (OS: Linux Mint 20.3) utilizing Firefox as the primary browser. This system has run almost flawlessly for many years. Updated to 20.3 in early 2022. Rather suddenly (yesterday) Firefox began repeatedly crashing, displaying 'Mozilla Crash Reports' (example attached). Firefox appears to initiate as expected. However, on display (e.g., Youtube, Facebook, web page, etc.) request, Firefox immediately throws a 'Mozilla Crash Report'. I do not recall any changes to the system that might have generated this condition, and have spend most of today unsuccessfully troubleshooting.

MB: Gigabyte F2A85XM-D3H CPU: AMD A-10 5800K APU with Radeon HD Graphics OS: Kernel: 5.4.0.170 generic x86_64bits; on 128MB SSD Firefox for Linux Mint mint-001 - 1.0 (122.0 (64 bit)) RAM: 7 GB

I have attempted to follow some of the moz://a Support pages (i.e., "Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems"). I have noted that while in 'Troubleshooting mode', Firefox appears to behave as expected, seeming to implicate extensions, themes and/or hardware acceleration. However, under normal Firefox operation enabling/disabling these does not seem to resolve the issue.

    * Hardware acceleration (on or off) still results in display of 'Mozilla Crash Report',
    * Default theme is selected, and
    * I don't appear to have any unaccounted extensions or other addons enabled.

Any thoughts and/or additional guidance would be greatly appreciated.

On certain websites I notices I have 'unknown errors' when trying to log in.

Usually this is remedied by either using Chrome or clearing cookies and the cache.

Both of there are inconvenient and result in a great deal of wasted time.

The usual response by these websites is "get Mozilla to fix this".

I'm getting sick of this.

I don't want to switch to Chrome but I will have to if this persists.

Firefox isn't loading anything, not even the about:configs page, this happened out of nowhere, i tried reinstalling it, restarting it but nothing is solving the problem, im using the lastest version btw

After updating to Beta 122.0b3 (64-bit), the active tab is now highlighted with a simple white outline instead of the coloring surrounding the address bar. My selected theme has not changed, and the same goes for all of my extensions. I could not find this change in the 122.0b Release Notes.

If this behavior is intentional, is there any option to return to the previous behavior (including in about:config)?

I have been getting this error message for over a week now, PR_END_OF_FILE_ERROR. My internet is fine and I have restarted my computer a few time since the problem started. I have added some sites to the Exceptions list but even then they don't work properly. I have tried refreshing Firefox and changed the profile and they both didn't fix the problem. I am sadly not knowledgeable enough to make sense of the Web Developer Tools. The attached image is what my YouTube page looks like after add the site to the Exceptions list.

When visiting some smaller and less known websites on my computer it shows the error message "connection has timed out" but on my laptop it loads just fine. Both run firefox and are sync'd with the same configuration and extensions. I already tried the troubleshoot mode and also checked the firewall. Is there anything else I can try to fix this?

This is my story. Digital affairs are serious problems for a marriage, although sometimes, they are also a symptom of underlying problems. Either way, you may quickly end up needing a divorce lawyer’s assistance if you do not put a fast halt to what is happening. Previously, traditional notions of infidelity required an actual physical relationship between an unfaithful spouse and their romantic partner. Thanks to the chxhack @gmailcom who helped me to dig into the communications of my husband platforms like his phone and social media, that i discovered that he was hacking extra affair and i got all the records of the communications and i was able to save my marriage. therefore if you are experiencing such worries get intouch with above. thank you.

Please my firefox appears to have crashed, or is not working how can i fix it. As i try to open firefox document a dialogue box appears saying that either the firefox is not designed to run or that i should reinstall firefox

After installing Update 123.0.1, History and Bookmarks no longer show up in the search bar even though they're still checked in my Search settings. What could be causing this? Thanks!
