Hey folks, I've been noticing something peculiar with Firefox that's been bothering me lately. Whenever I try to watch videos on YouTube in resolutions above 1080p, they tend to randomly buffer. It's quite frustrating, especially when I know my internet connection is stable and other browsers don't seem to have this issue. Has anyone else experienced this problem with Firefox? And if so, do you have any tips or solutions to share? Thanks in advance for any insights!

I'm having trouble using my bank's website. Sometimes I can't log on (error messages) or I can log on and can't use certain features. The bank is Regions. The site works with other browsers. Is there some setting on the latest Firefox that needs to be adjusted? The articles I've read don't help. Thanks.

I am trying to add custom search engines to Firefox. I have tried the steps given in the forum thread https://support.mozilla.org/en-US/questions/1212596.

However when I try to go and add the search engine as per the article given above I do not get the option. Please see the attached screen shot for more details. I do not want to add an extension or a plugin, but just manually have the option of adding search engines.

This is almost surely a "security" or "privacy" design, but it's an error. In Firefox - only (this works fine in Chrome) - if I open the LastPass Firefox Extension, find a Site, and Copy the password, then go directly to an open AnyDesk remote access connection, and Paste (or, lightning bolt menu, Insert from Clipboard), what gets pasted is a single wrong character, NOT the password that IS in the clipboard. (If I paste instead into e.g. a local Notepad window, the actual password gets pasted). I asked AnyDesk support about this, and they confirmed that it's something that Firefox is doing. It shouldn't. Copy is copy. Paste is paste. Why would Firefox do something so that copied text (which just happens to be a password from a password vault extension) pastes wrong when the destination just happens to be a remote desktop client (AnyDesk) to send the password through to complete a login at the remote end? Anyway, how to turn off this wrong behaviour? thank you. (Windows 11 Pro, 64-bit, 23H2, Firefox current - 125.something today, but this has been going on for some weeks at least, AnyDesk version 8 current)

How can I set the default language fir Firefox to English? Currently browsing results always come up in language of my geographic location, for example, Romanian while in Romania. Never had this problem before.

Starting a couple of weeks ago, I began noticing that occasionally (every 2-3 days usually), a few empty files appear in my c:\ folder (Windows 10, as up-to-date as Windows ever is). They have names like "wal3A7109C6" (no file extension). Usually 4-5 will be generated at the same time (ie, same timestamp, so within the same second).

When I first noticed them, I (nervously) deleted a batch with no apparent consequences - but I had to activate Administrator privileges to get rid of them. I ran virus scans but have seen nothing unusual.

A few minutes ago, I had Firefox open but minimized to the task bar. I also happened to have c:\ open in a Window I could see. As I tapped to expand the browser, another of the files appeared, and the browser window behaved oddly for a moment, as though about to crash. The last few versions - I'm at 125.0.3 (64 bit) - have been crashing more than I'm accustomed to, but this is the first time I'd considered the browser to be a likely suspect.

Does anyone have any clues/possibilities to offer? It would be much appreciated.

May I first say that trying to get hold of you to make this report was painful, and took about 20 minutes and a long walk around Mozilla's assorted website, opening two accounts, etc.

I received a notice while using Firefox on PC that an update was available. I was going to put it off, as I had 25 tabs open, but the notice indicated that my open tabs would be restored once the update was complete, so I approved the update. It download and I assume installed the update, seemed to temporarily close Firefox, and then reopened the original page with all my open tabs, plus an empty page. When I tried to open the tabs shown, they all indicated that the tab had crashed and then gave me the option of restoring that tab or on some restoring all tabs. Neither worked, in fact, that Firefox page became completely unresponsive and would not allow me to browse new urls (the tabs just spun). I actually had to use MS Edge to get to anywhere to seek out someplace to make a report. I first went to the discussion group and opened up an account there, but from there noticed that feedback on Firefox was at a different url. I then needed to create an account "here". Since nothing was working, I closed and reopened the Firefox page with all the tabs on it, figuring maybe it would restore the crashed tabs. It did not and all tabs were lost. I can probably get back to some of them using the history archive, but it was very disappointing and will be even more time consuming. I am running the current version of Win 10 pro, 64 bit, on a PC. I thought you would want to know about this. Thank you for your time.

Hi. i have no results while doing this: https://dpaste.com/FTXPQ46ZL# No error, no screenshot. "Screenshot" flags in default state, about:policies - inactive.

Ok-So this popup window popped up when I returned to Firefox. I don't think it's legit and I am wondering how I go about blocking it permanently. I searched the settings but didn't see where I could post the URL so that is why I am posting this here.

I copied the URL but I don't want to post it here in case it could do something to someone else's system. But here is the screenshot. Please advise me what I need to do. Thank you! TGIF!

I am on a Mac running Sonoma.

I have used firefox for years as my browser with my home page set to google. I have always had a bookmarks toolbar but never a bookmarks side bar and do not want one. The other day a bookmarks side bar suddenly appeared. I have moved it from left side to right side and can delete it temporarily by using CTRL +B, but can't find a way to permanently remove it, i.e. make the default setting so that the side bar doesn't appear. can you help?

I post or write something on my homepage. I then want to share my post to groups I belong to. I hit the share button and get this new and poorly designed response to share. I go to the 'group' share icon. It then lists the groups I'm a member of. So far so good. I then click on one of my groups that I want to share the post with. I get a response, like previously before this new change, allowing to write something to the group along with the post/image I want to share. But there is no 'share' button that allows me to share the post. When this hideous new change came into effect there was a sliver of blue at the bottom, obviously from the share button, and clicking on this allowed me to share my post. Unfortunately, the next day when I attempted to share my post, the blue sliver disappeared and there was no way I could share it to a group. For some reason I cannot take a screenshot of what I'm writing about. Your thoughts?

After accidentally cutting power to my pc, Firefox has been crashing upon start. I've tried using Troubleshoot Mode, refreshing, reinstalling, and even manually deleting all my user data, but nothing has worked. These crashes do not appear in the crash logs, and happen instantly upon opening the program.

Oddly enough, using task manager to restart Windows Explorer stops the crashing, at least for thirty or so seconds (this is how I was able to try Troubleshoot Mode, as well as accessing logs). I have no idea why this is, nor if it's useful information.

Hi All,

Any idea why the menu code I'm using below to reduce padding in menu items is only affecting Firefox in Windows 10, but not in Windows 7?

Please see attached images.

It's a very strange anomaly. This is true for both FF 125 and FF 115 ESR.

Thanks to all who respond.

/*** Tighten up drop-down/context/popup menu spacing (8 Sep 2021) ***/ /*

 min-height: unset !important; /* v92.0 - for padding below 4px */

}

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

A bit desperate here. Windows crashed with no chance of repairing the installation. Hard drive And all files on it are accessible. Firefox had thousands of bookmarks for a very important project.

There seems to be no Firefox profile on the drive. Searched in hidden folders as well. Certainly not where it’s supposed to be: …\AppData\Roaming\Mozilla\Firefox\Profiles

Search for all files on the drive, but there seems to be no SQLITE or JSON files related to Firefox.

Not even a folder anywhere in the drive called Mozilla or Firefox or Profiles or Profile (at least not in relation to Firefox).

There’s no file called places.sqlite or bookmarkbackups anywhere on the drive.

The drive itself seems to be in a good condition and all other files are there and accessible. The file system doesn’t seem to be corrupt And man thousands of bookmarks were there before windows crashed.

Also checked places in \Roaming\ Just in case, as sometimes it could be found there for some installations.

Nothing found anywhere so far. Seems like running out of options.

Any ideas would be greatly appreciated.

Thank you very much everybody for your time and attention.

Some months ago, Firefox stopped displaying the blue progress bar that would normally show once you clicked on the download icon. You still see the usual file info but now the progress bar of the download is gray instead of blue and is extremely hard to see. You have to look closely but in the first screenshot you can see where the shade of gray of the progress bar changes, just under the "6" of the "x86" part of the file name. But if you click on the "show all downloads" link, then the blue progress bar will show as usual for any in-progress downloads in the Library window, as shown in the second screenshot.

It isn't a huge issue but is still annoying when you just want to quickly see the progress of downloads in Firefox. I haven't changed any of the colors in Firefox or in Windows for that matter, I'm currently running Windows 10. All other dialog boxes, windows, etc. all display normally on my system. Just curious if anyone else is having this problem and hopefully a future update can take care of it.

Thanks very much!

Hi!

I'm trying to determine if I'm having a Firefox issue or not. I've been using Firefox for many years and frequently use private windows.

I've got a new laptop with Windows 11 and have been noticing that my private windows are sometimes closing unexpectedly. After which, I can't get my tabs back. This has only happened with private windows, and not regular windows.

Is this an issue that's being reported in the community? Thanks.

OS version : Windows 10 Pro 21H2 Browser version : Firefox Developer Edition 126.0 Beta 8 (20240501022718) Platform : windows, Web

EVERYTHING especially

 * The time to receive the first HTTP response when connecting
 * the time to call up the various css elements that make up the screen
 * the time to call up the img elements on the screen
is too slow.

tooooooooo slow. I waited 36.6s until http response for every new URL open! Of course, I am using a lot of Firefox extensions, but there were no serious problems outside of YouTube, and the same problem occurred after removing the extension, and i also confirmed that the problem caused by web extensions on waterfall(on firefox profiler) was minor.

I can't even guess the cause of the problem, so unfortunately there seems to be no additional information that I can give you. I'll keep following up as long as I can. I will attach some pictures that might help you solve the problem. and you can also approach to my full-recorded firefox profiler data

Do Firefox menus appear differently in Windows 10 than they do in Windows 7?

In Windows 7, I see the normal system menus - square corners, light blue menu item highlights, 3D column line on the left, dark drop shadow below and to the right of the menu.

In Windows 10 I notice differences - gray-highlighted menu items, rounded corners, no drop shadow, etc.

I'm not using any code to style the menus.

Please see attached images.

Thanks to all who respond.
