Problem: when I make new firefox window(launch .exe, drag a tab out, shift+left click link...), there is tiny gap between screen edge and new firefox window. (fullscreen works ok)

Expected behavior: no gap between screen border and new firefox window

Image 1: firefox window snapped to right. Image 2: new firefox window after minimize right-snapped window. Image 3: firefox window across left screen border. Image 4: new firefox window after minimize across-left-border window.

Tried: edit&delete xulstore.json, reset firefox, uninstall and reinstall firefox. still same issue

i can't get firefox.com/pair to show on my desktop.

I have just reinstalled MS Word on both PC & phone, (as something has gone wrong with my somewhat elderly PC). My phone (Samsung) says to connect mobile device with my Mozilla account, then I need to open Firefox on the PC, visit Firefox.com/pair, and follow the instructions to connect the mobile device.

I can't find firefox.com/pair on the PC.

For a few months, and I've seen this happen randomly over the last 5-10 years - pressing enter doesn't work, and sometimes dragging a new link into the empty tab space next to the tabs creates a new tab with the URL in the URL box, but not 'opened'

Does firefox have some issue with loading a web page?

I use ublock origin on default settings, and violent-monkey and stylish for scripting.. but would that disable searching google from a new tab?

I’m getting “'Gah. Your tab just crashed’” basically every other website I open (including this one). I don’t notice anything in common with the websites I’m visiting and it’s happening in the troubleshooting/safe mode as well. I’m using the most recent version of Firefox and am running MacOS 12.6.

Please advise on how to remove osite data

I do the following but it fails to remove website info

Setttings -> Privacy & Security -> Cookies and Site Data -> Clear Data check all options Clear Data -> Clear go to Manage Data ~ 12 sites are there with last used show 2 & 3 years ago Remove All -> Save Changes -> Clear Now going back into Manage Data, all the sites are still there none of those sites are included under Manage Exceptions

How do I remove the old site info?

Since installing Firefox on Ubuntu 24.04 from the mozillateam-ppa, I can't simply open normal files like .pdf with my preferred OS-application (evince) by clicking the link. Instead a "File Link" handler (see attached image) opens for any such file, be them .pdf, .odt or whatever, and this handler only knows one default and has to be told all possible applications by hand.

How can I configure to Firefox to open any file by the preferred OS-application.

Apparently I sync'd from the wrong direction (machine) and my old MBP now has only one default container now. The dozen or so containers I had have disappeared. You need to be clearer in your directions and define the use cases. In my case I want to port over FF from an old MAC to a new MAC. This would include my settings, configuration history, folders, bookmarks, extensions, homepage, and my containers to a new MBP - so it looked like the old one. Eek I thought it would be smarter and see that the new MBP was a newer version and had no configuration. Now I have blown away the containers and have to remake them. I also notice now that my settings - home page, history are not the same yet so I will have to look into what is going on there.

I am disappointed with the way this is going. Your initial master sync should be clear, there is no way to see if it is done or running or completed the initial sync. Honestly, the master sync should be treated differently from intermittent syncs anyway. Now the containers on my old MBP are has changed to the original 5 or so default containers, all of my containers are definitely gone! I logged out of mozilla, since it is apparently breaking my good version of FF.

Please clear up the documentation and include the use case of porting to a new machine to include Containers.

What is the latest update? I have 2 Macintosh computers with the same lateste version of Sequoia (15.2) but different versions of Firefox (135.0b7 on MacMiniM2 and 134.0.2 on MacBookAir M2). Firefox settings set to automatic update but MacMini shows "Failed to Update" in About Firefox.

In the last couple weeks i've encountered an issue where video footage, but not the audio or the video progress itself, will freeze if I tab out of Firefox and into a game window.

Here's a video showing the issue

Like shown in the video, It only seems to affect Firefox and not other browsers, and it only happens when I switch to a game window, not other tabs. It should also be noted that although the video only shows YouTube footage, this issue affects every player I've tested it on.

I've tried this both with and without extensions enabled, as well as just about every video player related config in the about:config page, and with both hardware acceleration on and off, still with no luck resolving the problem.

If anyone has had a similar issue and managed to fix it, help doing so for myself would be much appreciated.

Firefox opens only to a blank page and does not function what so ever. I've tried several times refreshing it, however, nothing helps. Point of interest is Microsoft Edge won't open either and I am currently using Opera which is working fine. Any suggestions would be appreciated.

Why is my credit card blocked on my favourite shopping site? Everything was fine until the end of December. My cards are not blocked by the bank or Visa or Mastercard. I've checked many times. A site I haven't used for 6 months isn't a problem. How do I correct this? Thanks for reading this. I hope you can help. I appreciate that you are here. Marcia Green

There's a problem with video playback on firefox, where after a while/randomly, the thing happens as shown in the image. I've uninstalled intel graphics driver and reinstall, didn't work, I've refreshed firefox, didn't work, I've fully uninstalled firefox and reinstall, didn't work, and when the error occurs the igpu is at 100% usage (and ram/vram usage is not full). The whole firefox app will be laggy but not windows, and upon pausing the video only will firefox be free of lag, and a refresh will solve the issue. However, it will occur again once in a while, doesn't matter the resolution or volume, and not just youtube but all other video players. It does occur more frequently and predictably when the video is paused for some time, or when the computer sleeps for a while, and I think it has something to do with the way firefox handles ram. (just my guess)

The only fix that worked was setting media.wmf.dxva.d3d11.enabled to false, which is undesirable as it increases cpu usage by at least 20% as well as increasing my battery discharge. Other fix includes using other browsers, using my nvidia rtx on firefox, and (not totally sure) setting the resolution lower.

Also, after the error occurs/before the error occurs, firefox doesn't do that blink-in-blink-out animation when going fullscreen on video players (like chrome), which can be fixed by exiting the firefox application completely and restarting it. Refresh doesn't work here.

For a while now, several months anyway, many of the sites I visit work in Chrome but no longer in Firefox. The sign in or login buttons do nothing, petition submit buttons do not work, etc. I can enter information in the required fields, but I the send/submit buttons do not work.

My test page is the log in for a course I have purchased. Here's what I have tried so far:

    Turned off enhanced protection 
    Paused AdBlock
    Ddisabled Privacy Badger
    Whitelisted the site on minerBlock.

Still no joy.

Anyone have any ideas? Thanks, --elizabeth
