Firefox 社群討論區

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

Hi! i was wondering why my firefox reseted after reboot. i have all the important tabs and bookmarks for my university work, chores and articles, platforms that are mandetory on my uni. also, i was tinkering with partitions before the reboot because my steam didnt want to run any games. i was guided by the chat gpt with terminal coding to do get steam working even tho i didnt solve the problem. is there any way you can help me?

What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

Hello all, I have FF 152.0.6 in use on Fedora 43 xfce Qubes OS VMs. The only issue I have encountered is when I try to load the web UI for Proxmox Datacenter Manager. As soon as I log in to the web UI Firefox vanishes. I have tried this in troubleshooting mode with the same results. I can open the same web UI in a Debian 13 Qube and it works perfectly. The FF version there is v.140.13.0esr. These are simply the default versions that come with Qubes 4.3 templates. I can also access the web UI in the original Fedora Qube with Chromium browser with no crash. I have also tried a different Fedora qube with the same failure result as the original.

I can use Chromium but would prefer a streamlined experience with just one browser. I thank all of you in advance any thoughts or suggestions. I am a long time Firefox and Mozilla user.

Have a great day. SS

Dell desktop running Mint Mate 22. Bookmarks missing about 50% of bootups. Saved bookmarks to both HTML and JSON during an occasion they did appear, when they next were missing attempted to restore them via Library pop-up (Manage bookmarks). I could not determine a path to direct the system to either locally saved file. In Library, selected Restore, which then asks me to choose file, but none of the data fields accepted or acted upon input. re-installed Firefox but same result. Then clicked on the saved HTML file, multiple screens flashed on the display, with multiple items in the tray. The final result was the bookmarks were all displayed as expected, but since the problem has been inconsistent, unknown whether they will display on future bootups.

Wish to have guidance on using the Library pop-up to restore saved bookmarks when they are missing. Perhaps some knowledgeable user could post a step-by-step through the restore process.

Firefox version 152.0 : Firefox is continuously refreshing the page on a particular Website, in both Windows11 and Linux versions, making the site unusable ( unable to click anything ). The website loaded ok previously using Firefox and still loads ok using Chrome. Disabling extensions doesn't help, neither does deleting the cache and cookies. What changed and why? Is there anything else to try?

I start FF in safe-mode. I open a local page which includes only one URL. When I hover on this link I see (`tcpdump`) a DNS lookup being performed for this domain. I followed the suggestions from Mozilla but I still see this.

How do I stop this access.

I use FF "156.0 (64-bit)" on Fedora 44.

TIA

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

I can no longer enter a password on the login page at https://secure.bankofamerica.com/login/sign-in/signOnV2Screen.go. I was able to change my password but it didn't help. A BofA agent could not identify the problem and walked me through the login using Chromium.

Yesterday I switched on my PC, opened Firefox and the home page was black. See the attached screenshot. This is not caused by some accidental switching on of the dark mode. Dark mode is clearly off. Neither can I adjust settings to make the Google home page revert to its customary light grey shade.

This isn't a big deal, I know. And it has happened before and in a short period gone away by itself. Maybe it is to do with a glitch in the latest Firefox version. But it has an unpleasant appearance and discourages surfing.

My Chrome Google home page doesn't have this issue.

Can anyone advise on how to fix this unwanted black screen problem ?

Firefox popped up an offer to change the screen to dark, which I did. I don't like it, want to change it back. I went to settings but was unable to make the change.

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

I have albinism. Pure white backgrounds are not an annoyance – they cause physical eye pain and trigger migraines. Every time I visit support.mozilla.org or accounts.firefox.com, I am forced to endure #FFFFFF with no way to change it.

To anyone about to defend Mozilla blindly: this is about accessibility and eye pain, not brand loyalty, so do not silence me.

What Mozilla has done:

• Disabled extensions (Dark Reader, Stylus, Dark Mode) from modifying these pages – they are explicitly blocked by Mozilla's own Content Security Policy.
• Removed ui.systemUsesDarkTheme and layout.css.prefers-color-scheme.content-override from having any effect on these sites – they ignore prefers-color-scheme entirely.
• Left no about:config toggle to disable the forced light theme.

The only remaining workaround is a userContent.css hack with filter: invert(1) – which requires a visually impaired user to manually edit CSS files and restart the browser. That is not accessibility – that is hostility.

Security excuse – debunked:

• "We block extensions for security" – extensions are sandboxed. Blocking them on your own support pages is a deliberate policy choice, not a technical necessity.
• "We want a consistent brand appearance" – branding does not override accessibility. Forcing #FFFFFF on users with light sensitivity is a violation of basic inclusive design.
• "We respect prefers-color-scheme" – you do not. These two domains explicitly override it.
• "Users can just use Dark Reader" – you block it.

What I demand:

Make support.mozilla.org and accounts.firefox.com respect the system prefers-color-scheme media query. If you insist on light branding, add an official dark toggle in the site header – stored in a cookie or account preference. Stop blocking extensions from applying user‑chosen themes to your own sites. That is not security; it is control. You are a non‑profit that claims to value accessibility and user control. Your actions say otherwise. Fix these two domains. No CSS hacking should be required for basic vision safety.

Hello. I am using Linux Mint 21.3 cinnamon and Firefox 144.0.2 When I use Google maps and the yellow small pointer (cartoon) to go on a specific street, the window come black when shifting to street view. My only extension is disabled, hardware acceleration unchecked, cache cleared and cookies cleared. I have made fresh install and nothing help. Troubleshooting mode allow street view to work fine but normal mode don't work. Google chrome work good. Chromium work good. And finally, Firefox work ok on my Linux mint LMDE 6.

Any idea where to go to solve this issue?

Thanks for your support

linux, firefox, and duck duck go search engine---i want to stop picture in a picture. include every instruction like if i am to use the address bar, where do i find that?

Using the Firefox 151.0 Mozilla Firefox for Fedora. Updated as of 23 May 2026, I use just a generic FireFox. I don't customize it, I just use it as it comes from the Fedora distribution.

I cannot save images (right click menu "Save Image As"). Nothing happens when that is selected. This worked a couple weeks ago.

Downloads are supposed to go to ~/Downloads. Checking the setting for this, Go to the three-line menu > Settings > General > Files and Applications, under Downloads, the "Save files to" value is set to Downloads, but the Browse button does not work to reset it. Nothing happens when I poke on the button. I can select the text in the box, but I can't change it.

I found the help page for "What to do if you can't download or save files https://support.mozilla.org/en-US/kb/cant-download-or-save-files and went thru every one of the steps there. None of them make any difference.

Strangely enough, there isn't even a "Downloads button" in the top toolbar. If I right click on the top toolbar and select "Customize Toolbar" it shows a downloads icon as already being in the toolbar, but when I click Done, it goes away.

Firefox recently had an update, and now when I am uploading files, I can't double click to upload selected files. I have to first select the file, and then click the open button.

Before the latest Firefox update, I could simply double click on files to upload. This workflow was much faster.

If I go to about:config, and search for: widget.use-xdg-desktop-portal.file-picker, I can change the value from 0 to 2, and then I can upload files by double clicking. However, then Firefox forgets my last upload location, and always opens in the home folder.

If I set it back to 0, it remembers my last upload location, but I can't double click to open files.

My current Firefox version is 152.0.1. Any help would be appreciated. Thanks.

I'm on FF 154.0. The power went out here and when it came back and I booted the desktop computer something had changed in FF.

I used to see the active tab as green in the tab bar and yellow for the rest, but now they're all gray until I mouse over the bar and only then does it turn green/yellow.

I struggled with this for many hours trying many //active tab color// solutions I found in searches but nothing got it back to my old behavior.

So as a last resort I tried adding the Firefox Color extension, but when I click Add to Firefox it just turns into a throbber that never changes so it doesn't install. I'm stuck!

Frustrated!!
