I-Firefox Community Forum

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

After an update of both macOS (to macOS Sequoia 15.0.1) and Firefox Developer Edition (to 132.0b3 (aarch64)), the Bookmarks Toolbar stopped working. The same issue appeared on my Windows PC.

Bookmarks toolbar is visible, I can show and hide it but it does not display any of my saved bookmarks. Luckily, they were not deleted and I still can access them via Bookmarks Menu, which is less than optimal.

The Drag&Drop functionality does not work either. When I grab the opened Tab, drag it on the Toolbar and release it, the Tab gets opened in the new browser window and it's not saved.

It's a bit weird, I got the thing you get when you migrate to a new browser - asking if you'd like to migrate history and bookmarks. I closed it because I've used Firefox for years.

When Firefox opened proper, I got a tab asking to restore the previous session, along with a "Welcome to Firefox" tab. As well I got a few popups for other things, basically just stuff you see when you open Firefox for the first time. A couple of extensions opened up a landing page that should only open when you first install them.

All my bookmarks and browser history is there. The settings have all been reset to default. The extensions are there but all of their storage seems to be gone, like my dark reader extension no longer has the exception sites on it. Ublock has the ad count reset and most importantly all my custom rules are gone! I have spent years making hundreds of custom rules, and quite a few took hours to get right. I am sad about losing that.

Does anyone know what might have happened?

When I was looking at my about:config to see I saw these things in the modified settings.

there's quite a few settings here and IDK which are relevant. The ones in the pictures where just the first couple and I show them because they seem to have something to do with this situation "auto migrated" - when it seems like the browser did this because it thinks it migrated, the first screen I got was asking if I'd like to transfer my bookmarks and history (and good thing I closed it,or it might have deleted those too).

When a firefox window is active on my second display, I lose the firefox menubar on my main display. I haven't noticed this before, is it something new, or have I inadvertently changed a setting?

Hello,

I had a crap ton of pinned pages for a long time. I restarted my computer and now they're gone. I've restarted my computer before with no issues. Pinned pages are supposed to stay no matter if you turn off or restart. How can I go about getting them back?

Thanks,

Hi....

I've been using the same firefox (installed every update) for over 10 years now and a lot of bookmarks have been accumulated. They are from different sources for different reasons/subjects/interests etc... I think when I reached ~430.000 or something like that it really slowed firefox down in a way that even clicking on a folder in the "bookmark symbol bar" (the one underneath the URL address fiel) takes 2-3 sec to open up and show the containing bookmarks. In the bm-manager going from one folder to another also takes a few seconds. I've now deleted about 40.000 but no change it's still lagging. and deleting 1000 takes about 1h.

I've looked but so far I couldn't find another tool or a better way to manage all these URLs WITH their title.

I still want to keep them, but managing them has become so slow and tedious. So if you have any suggestions especially for other tools to manage them....

I also think the possibility to export only a part of them (selected ones, or specific folders) would be helpful; maybe also a tool to clean up the database? (like defrag did for harddrives?). or split it to differnt files? I don't know.

I know 400.000 bookmarks are extreme... but well....

I have read through the user threads and tried everything I could find including malware searching and, of course, setting google as my search preference but no matter what I try the splash page for Firefox (re-installed twice) is Yahoo. Has anyone found a cure for this issue on their Mac - my Mac parameters are in the attached screenshot.

Thanks for any sage wisdom!

I've been seeing this more and more, but my toolbar will change by itself every restart. The add tab button will shift all the way to the left or not appear, the bookmarks won't appear, etc. I'm not sure what can be causing this, and I saw no way to "save" my current configuration other than pressing the done button upon using the custom toolbar, which I had done every time prior to fix my configuration. Does anybody know why this is occurring, and a possible fix? Thank you

Hey guys, I'm using Ubuntu 24.04 with Firefox 124.0 .deb release from this repository: https://launchpad.net/%7Emozillateam/+archive/ubuntu/ppa I enabled "Ask whether to open or save files" from settings. Whenever the Open/Save dialogue is shown and I choose Open, I expect that the file would be opened using the default application. But Firefox asks again to choose the application by which the file (file link?) should be opened. It seems that Firefox is somehow change the way the files are opened through external applications and transformed local file addresses to file://uri/on/disk.

Firefox stop from 2 days ago read Google Recaptcha, from nothing.., Dev version to.. I have the last 126.0b8 and both not working, I try disable Tracking Protection and still, clean everything... spinning forever...

I try my Firefox at mobile, that works. I need Firefox working on this. Cant use Chrome...

Help!

Up to 126.0b9, files with encoded URLs in their filenames downloaded normally. As of 127 onward, however, it gets changed to _3A instead of %3A, etc. Is there a setting somewhere in config to revert this?

Example:

Supposed to be: test [sound=https%3A%2F%2Ffiles.catbox.moe%2Fe547nk.mp3].png Downloads as: test [sound=https_3A_2F_2Ffiles.catbox.moe_2Fe547nk.mp3].png

Hi all,

I'm using Firefox 125.0 (64-bit) on Fedora and for file downloads, I have the options "Ask whether to open or save files" and "Always ask you where to save files" enabled.

This basically works, Firefox opens a file selection dialog and I can select where I want to save my downloads - so far, so good.

The weird thing is, the default location that is shown in this dialog seems to change every time I download a file. I would expect to see the last download location as the default option, but that is not what happens.

When I check about:config, I can see the last used download path is saved as browser.download.lastDir perfectly fine, but it is not set as the default for the next download.

Is there a parameter I can set so this last path is used again?

Thanks,

M.

System OS: Debian (codename: bookworm) Problem description:

I had installed a fresh version of Firefox and it's keeping to crash the pages (Error: The page has crashed) without any reason. Any troubleshoot methods (including clearing the cache, cookies, history and even restarted the network and pc.... only to fail and keep having same issue.

I had checked if there is no problem with the opened website in another web browser and in it the page was working correctly.

The issue persist from several versions of Firefox

I have had this problem for a while. I am not sure what to do so that I can fix this. Whenever I open a pdf or any application that can be opened in the browsers shows me two options for firefox browser. I attached a picture that will make it obvious what the problem is.

For years I had my Firefox sync working fine between Win10 PC, Android and several Win10 laptops. However yesterday I installed Windows 11 on the same PC I have Windows 10 (bought new disk) just to have a fresh install. Started with installing firefox - and here when problems begin. It couldn't let me log in into Sync, I was being immediately logged out ("Account disconnected"). Somehow I managed to log in, but then all my previous data was erased (passwords, bookmarks). I thought ok, maybe later it's gonna sync. Started installing extensions, saved one password. When trying to sync tabs with Android phone it didn't work, it couldn't see any tabs (but it could share tabs between devices!). On Android I still have old passwords and bookmarks saved, same as on old Win10 (on which I got logged out). Alright - it didn't sync after restart so I removed Firefox profile on machine, started again with logging in - and it synced only ONE password that I saved previously on same Win11 machine, with extensions I freshly installed back then. So it saved to sync improper data, forgetting about old? Logged out from all of my machines in Firefox Account. Now I'm back to my original machine on Windows 10. And what? I can't log in! Same error as on Win11 after install - "Account disconnected". Checked about:sync-log and found error logs - pasted into "Troubleshooting information" of this post.

Thanks

Just updated my Mozilla Developer and it removed my bookmarks (the tab is visible but has no bookmarks, and restoring them from backup doesn't do anything) also the extention button is for some reason on the left side (it was on the right side) and the "+" button was missing, had to re-enable it (AND IT'S ALSO ON THE LEFT SIDE FOR SOME REASON)

Wtf happened
