I have Firefox 115.1.0esr on Windows 7 desk top PC. When I try to log in to my Comcast Xfinity online account they say my browser certificate is invalid and I can't log in. Any suggestions? Thanks

I'm using Windows 7 and have been migrated to the esr updates for Firefox. I think this problem started cropping up just before going to the esr versions, but not sure. Firefox will a) randomly hang and do nothing for 5-10 minutes and then pick up fine b) tends to hang a lot when signing into websites like banks, etc, doing the same thing as (a). I've updated FF several times since then, but same problem. I did try to do 1 fix which suggested creating a new "places" database, but that did not solve the problem. Not sure where to go from here as nothing has changed on my computer since the problem started - no new software, etc.

Speed test on a freshly booted machine is 100/100Mbps ... very often after viewing a youtube video in Firefox, this Speed test can slow down to below 20Mbps which results in a poor streaming experience ... I have a 150/150 fiber connection and the modem speed test doesn't change ... nothing to do with anything downstream ... not running anything else except FF ... always running with the latest up to date version(s) ... things of note: the process count goes up when this occurs ... even if FF is restarted it doesn't resolve this issue ... only a reboot resolves the issue ... when rebooting there is always some UNKNOWN process that needs to be manually terminated before the reboot process runs.

I suspect one of the multilayered (FF appears to open multiple sessions with streaming) processes may be getting widowed and left running and not releasing resources which causes less and less bw to be available ... this appears to occur mostly if I either Fast Forward or try to click forward or backward on a stream timeline suggesting to me that the current timeline may not be closing properly ... process manager doesn't reveal any processes linked to firefox but there are numerous svchost processes which I expect may be involved

Are there other ways/tools to narrow down this issue so the Mozilla team might be able to fix this ... I use FF exclusively but this has become more and more of an annoyance.

My i7 2TB 2.6GHz 8GB laptop is unable to move beyond W7 64b pro but I have had the same experience on a W10 64b Pro machine so very skeptical that this is an OS related issue.

Ultimately if FF kept track of the PIDs it opens it should be able to force them to close if they refuse to close on their own. Kill Process tree ... or ... perhaps provide a log that is user accessible identifying opened PIDs so that a user could manually kill widow processes without having to reboot.

It loaded and played OK prior to this update.... works mighty fine on another browser, if this is not fixed I'm through with Mozilla AND you can remove my account!

Looking in task manager-: Firefox.exe 45,24K Firefox.exe 3,16K Firefox.exe 27,484K Firefox.exe 7,392K Firefox.exe 7,344K Firefox.exe 15,735K Firefox.exe 7,320K Firefox.exe 169,932K, I round it off to about 250MB

Yes I cleared the cach, I change profiles..... as said by each update about:config gets bigger and bigger.

I used to like Firefox because it let me set my browser up in an intuitive and comfortable way, and it was able to easily do the things I wanted to do. Then simple and useful features (e.g., tabs under the address bar) were hidden in about:config. Then they were removed completely, and you had to use third-party extensions to restore them (e.g., getting the refresh button on the address bar). Then, the third-party extensions were blocked so that you had to copy and paste third-party code into userChrome.css (e.g., restoring "View Image").

I hate updating Firefox, because it gets worse every time. This browser has turned to absolute garbage, and it just keeps circling the drain. Wasn't Firefox supposed to be the customizable browser? Mozilla seems to have decided that customization needs to be completely wiped out, and features need to be removed for...some reason?

Why is this happening? I shouldn't have to be afraid of the update button, but it's become a "make Firefox even worse" button. My only consolation now is that Mozilla won't have any more major updates for my operating system, so I might be okay for a few months.

It astounds me that there is not a dedicated article on this subject. I did an internet search - 'Infinite Scrolling Complaints'. Usability Issues Caused by Infinite Scrolling =

What kind of an engineer - in their right mind - designs a web page navigation system that

Why is there zero zilcho nada discussion about this?!? Thank you, Mozilla Firefox, for your consideration.

I use an IRS web site to pay taxes. I can not get in. It says I have to use a browser with TLS1.1 or 1.2. Dose firefox use this. If not how can I get it?

Thanks Galen Alldrin

OS = Windows 7 Pro. Web-browser = Firefox. Both worked very well for many years on desktop PC and laptop. Recently desktop PC repeatedly reported "Windows Explorer has stopped" whenever Firefox was started. Today I updated Firefox on my laptop after several weeks of non-use. "Windows Explorer has stopped" appeared immediately Firefox started - error never seen before on the laptop. Could the most recent update to Firefox be the cause of this fault?

Deleting autofill entries does not work per article. The info is still there. Clearing history does not work either. Do I need to restart computer for it to forget/delete entries? Thank you. Fred couvrette

After Firefox update 115.2.0esr (20230821110938) was installed on 9/8, I could not properly access my online banking accounts. Installation of Firefox update 115.2.1esr (20230912014149) on 9/16 did not resolve the issue. Can these two updates be uninstalled? I was still able to access my online banking accounts after Firefox update 115.1.0esr (20230724124053) was installed on 8/8. I want to revert back to that point to see if this will resolve the issue.

Thank you!
