I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.

Where can I download a fresh Firefox 115.33.0esr (64-bit) browser for Win-7 because the one I have installed is so corrupted and I can't seem to be able to fix it.

When I play YouTube videos in Firefox, they are constantly choppy and slow, even though my internet connection is fine and other browsers (like Chrome) work smoothly. This happens with both HD and lower quality videos. I've already tried clearing cache and disabling extensions, but the issue persists. Please help me fix this.

My name is Dr Tahmeena HazratyOmid. I use Firefox on my Android phone. Recently the browser became slow and YouTube videos do not play smoothly. I tried restarting the phone but the problem is still there. Please help me solve this problem.

In their info Google say the CSE (Client Side Encryption) isn't up to date and won't work. My About Firefox link tells me I am up to date.

Does anyone know what is going on here and how it can be fixed please?

I am encountering more and more websites with problems they attribute to Firefox. Many of them recommend using Chrome or Edge and some insist upon it or they will no longer support problems. Direct TV will no longer work with Firefox at all and they will not fix it. Several of my other regular websites will work partially, but have pages that simply will not work with Firefox. I have resisted using Chrome or Edge for years but it is getting harder and harder to do as on line systems continue to have problems with Firefox and their only suggestion is to use Chrome (which works when Firefox doesn't). Any ideas/suggestions?

When I play a video in fullscreen and type something, when I typed something in the IME and will press Esc to quit the IME, the whole fullscreen will be quitted. The expected behavior is to quit the IME only, and the fullscreen should be quitted only when there is no IMEs.

The issue has been existing for years.

Hyperlinks keep opening in new windows, not in the same/existing window where they were selected. Issue is not unique to Google Search results and occurring across multiple websites. At wits end trying to figure this one out. I have deselected the "Open links in tabs instead of new windows", turned off all extensions, and uninstalled & reinstalled Firefox. Issue is still occurring. Attached is image of my tab selections showing all turned off.

The last 2 days when I have shut down my computer then restarted, my Firefox profile has disappeared, along with all my bookmarks, passwords etc. I spent several hours yesterday following all the advice here to get everything back, but nothing worked. I had to create a new profile and then import an old passwords file, which I luckily had saved in Excel. This morning when I switched the computer on, the same thing has happened. I cannot even open Firefox without creating a new profile. I get a pop up box (screenshot attached), which shows no profiles, and i have to create a new one to even open Firefox. Every time I close out of Firefox and want to go back in, I am asked to choose a profile. This has never happened before.Before i give up forever on Firefox and go over to another browser, do you have any ideas how i can stop this from happening, and get my original profile, passwords, bookmarks etc back? Thanks.

I am attempting to access a website https://my.calbrightcollege.edu/ however when i attempt to sign in i get kicked out with the message below.

Something doesn't look right!

Refresh the page to reload the student portal.

Or contact support at 1-833-956-0225 or email us at success@calbright.org.

I reached out and was advised could be something wrong with the software however I believe I have the latest software as i just downloaded the browser today. I am also able to access the same site on my phone and my IPAD not sure why it wont work here.

This afternoon, I clicked on a link from an email and for the first time got a choose a profile pop-up. I do not want this; I have read info on Mozilla and elsewhere about its purpose but it doesn't say how to just stop the pop-up - there should be an option just stop the pop-up because I don;t want to have to choose amongst options. I have started copy-pasting the links in emails and going to Chrome and will seriously have to reconsider using Firefox of this continues. I don't want to have to type about:config or anything - this should have been an opt out or opt in thing and I want out. Thank you for your help.

When watching a video on a platform and the video needs to load, instead of pausing to load then play it once again, it doesn't stop, making the video audio sound so glitchy that you can't understand it

surprisingly, it works as expected on youtube

Mozilla-Team,

I am / was such a huge fan of Mozilla. But now I lose my qualitity of being patient. This Update window coming up more and more. But there is no way to find - especially not an easy way. I need to make a new installation of the full programme. While doing this, I lost my full bookmarks. No chance to recover after five hours. I am really mad. Really mad.

I will leave Mozilla soon, if you dont tell me, how to use your browser without trouble.

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

Windows 11 : Fix this ASAP I delete all tabs, close firefox, reopen and I get 5 tabs which seem to be STUCK. I delete 3 of these tabs, go about my work, none of those 3 are open, and I shut everything down. When I reopen Firefox, those 5 "default tabs" (the 3 I don't want have migrated over from I don't know were - both Chrome and Edge open with New Tab.)

I have enough other problems in my life - and done't tell me to create a new profile. At that point I'll kill firefox and end my donations to Mozilla.
