iOS 15.8.3, FF Version 133.2.

A couple of months ago I started having a bunch of issues with the iOS app simultaneously. First I couldn't get my tabs to sync. Then I signed out and had a hard time signing back in-- it just wouldn't work. Now I am finally signed in, but the app isn't working like it used to. I haven't been able to sync tabs since then now matter how many times I try. It still shows tabs for stuff I read months ago. I can't send tabs from desktop to my phone (but I can send from my phone to desktop with no issues). Finally, the tabs are all weird now-- they are huge (see pic).

I have tried uninstalling and reinstalling 20 or 30 times. I'm considering going back to Safari because the main reason I use Firefox is for phone/desktop connectivity and it just isn't working anymore. Any ideas?

I have just installed Firefox on a new iMac, running MacOS 15.2. Firefox will not load any of the websites I have tried, whereas Safari and Chrome do. I have cleared the History and also set "No proxy" but loading still fails.

I am trying to access iDRAC 7 on a Dell Poweredge R520. On version 133.0.3 I get a An error occurred during a connection to 192.168.1.20. PR_END_OF_FILE_ERROR. I know that the problem is that Firefox stop supporting older versions of TLS. So I choose to also install an older version of Firefox (43.0). On that version I get a The page you are trying to view cannot be shown because the authenticity of the received data could not be verified error. I used to have no problems accessing iDRAC 7. Has anyone else been able to resolve this problem?

After months of constant Thunderbird crashes and hundreds of crash reports, and as many attempts at trying to resolve the issue but without any resolution, I am now getting the following message when Thunderbird crashes:

Thunderbird had a problem and crashed. Unfortunately the crash reporter is unable to submit a report for this crash.

Details: Expected value at line 1 column 1

I have version 128.5.2esr installed, but the issues started well before this version you can see the information in the crash reports if you want to look at them. I have tried Troubleshooting Mode, and can confirm the issue persists. I have also noticed that the one IMAP account I have attempts to redownload all messages from the mail server - it never completes because Thunderbird always crashes first. Aside from the obvious request for troubleshooting suggestions on the primary crash issue, I have three additional questions:

1. Is there a way for me to isolate that IMAP account, in another profile or such, to see if that account or server is contributing to the issue?

2. How is the crash report interpreted - i.e. where do I look to see the actual cause of the crash? In the "Details" tab the CRASH REASON and CRASH ADDRESS are not very informative to the average user.

3. What is the best way to provide a list of crash reports - I've had nearly 30 over the past few days, and - literally - hundreds since the issue began in October (which did not appear to coincide with anything in particular - e.g. new hardware or software, or TB update. Is is acceptable to post a list in the body of this thread, or as a txt document, or .... ?

BTW, running this on a Windows 10 22H2 machine, i9-14900KS, 32Gb DDR5, previously nVidia Quadro P5000 now Intel Arc A770 Graphics. Yes, have tried rebuilding POP3 folders, and yes I have a backup of my profile, which is about 35Gb in size.

TIA

I believe this problem began in 133. I've noticed that if FF is open for a few hours, it starts to develop a very noticeable input lag. For example, if I'm watching a YouTube video and hit an arrow key to advance the video, there will be a couple of seconds before the browser registers the key press. It behaves like a high CPU issue but I do not detect high CPU usage when this is happening. Restarting the browser resolves the issue for a few hours.

This is happening on Windows 11 as well as on a Mac running Sonoma.

On YouTube tabs, if Firefox memory usage starts climb (ie. more than 3-4 tabs active), there are janks for a few seconds preventing me from interacting with the YouTube tab. This jank does not happen with other tabs (can even interact normally with other tabs while the YT tab is janking). Attached is a profiler report.

When I pull upwards on the bottom of my screen to scroll between/close apps while in landscape mode (such as watching a video or playing an app), if Firefox is open it will show me a preview of a video that I watched a while ago (and in a private browser, as I do most of my internet usage in the private browser). Why is it doing this? I've since watched other videos, and yet it still shows the preview of a video from several weeks, if not months ago. I'd like it to not do this. It's a bit annoying seeing this glitch (or occurrence, however it may be categorized) so often when I'm long since watched other things. It's only occurring when in landscape mode as well.

Hi Mozilla friends,

I'm running OSX 10.9.5 and I just can't afford to buy another computer right now, all the more that my iMac works beautifully. I tried and cannot install the current Firefox. What am I to do? Many thanks, - Greg

Every so often for the past few days this "unfinished" program window has appeared on my pc on top of a normal Firefox window (see attached png). Does this have something to do with Firefox? I think the same thing appears when I first open Firefox, then it gets "filled in" and appears as a normal Firefox window. I am running Firefox 133.0.3 (64-bit) on Windows 10 Pro Version 22H2 build 19045.5247 Windows Feature Experience Pack 1000.19060.1000.0.

Hello. Today suddenly sound stopped working on Youtube and tried changing volume as well made sure there is no muting. I tried opening videos on Youtube via Chrome and sound was working fine. How to fix this issue on Firefox?
