Firefox Support Forum

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

So, this is going to be an incredibly weird question, but is anyone else having this issue? As of about two days ago, any time I try and load a video on youtube it will refuse to load for upwards of 30 seconds, however if I toggle the new stable volume option off/on it instantly loads. It will then play for about 2-3 minutes or more depending on video length (sometimes way more) before the buffer bar will stop entirely, take over two minutes to load the video again, then keep playing. More often than not doing this multiple times per singular video. Often times it won't even load anymore at all and I am forced to refresh the page and toggle the stable volume once again.

I've tried disabling every single extension I have, including ad blockers, restarting the entire browser, and using a different account, and it still happens no matter what. However it is not an issue that occurs on chrome or edge, so I'm at a complete loss of what is causing this. Looking up this issue comes up with next to no results, so is it possible this is a youtube issue or is something seriously wrong with my browser and I need to re-install it?

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas

In Firefox, after a reboot, how can I re-open my previous sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previous sessions.

Usually I just open Firefox, and this opens one browser, and then all of my previous browser, and tabs reopen, but this time Firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tabs, but it didn't.

After following the usual Firefox help guides, it still wouldn't re-open my previous sessions. Now if I ask it to open my previous sessions, it just opens the recent help guides, and not anything before the crash.

So is there a backup file of my missing sessions that I can roll back to?

I am finding more and more sites that I regularly go to are no longer working on firefox. One site was because HTML5 apparently does not work on firefox. But others I don't know about why are no longer working on firefox. I thought it might be streaming related but just today I could not access one of my banks on firefox, and I tried many times, but had no problem signing on using Chrome.

Im using Ubuntu 22.04 LTS Intel cpu I7 9th gen NVIDIA gpu but i disabled it My problem is that the Picture in Picture mode isnt sticky if i press anything it vanishes from view.

I have been having consistent issues with Youtube when played on Firefox. Opening the "Stats for Nerds", I see that I have decent connection speed. However, I get a burst of network activity, and then it stops. Therefore, i can't watch the video. Refreshing Youtube does not help at all.

Trying on other browsers, I do not have issue. While I sometimes get low network activity, most often than not, I can play Youtube videos fine.

I have done the following:

• Confirmed that I'm running the latest Firefox version (127.0.0)
• Cleared Firefox cache
• Confirmed having issue (sometimes worse as I get no network activity even on refresh) on Firefox Troubleshoot mode

FireFox just updated itself to the latest version (127.0.1 (64 bit)) on my Windows 10 laptop. Now every time I try to close it, instead of closing, it starts a background process and then crashes after about 25 seconds.

Hi Team,

Would love to know how in task manager there are 10+ firefox services running with only 4 tabs open and the usage is ridiculous. Closing one tab the next one that was using roughly 250mb shoots to over 600mb...what are you playing at????

See attached.

This problem started yesterday. Whenever I try to connect to a website, I'm met with an error saying "Secure Connection Failed", each time with a different error code. Dropout.tv gives me PR_END_OF_FILE_ERROR, Netflix gives me SSL_ERROR_RX_RECORD_TOO_LONG, DuckDuckGo gives SSL_ERROR_RX_UNEXPECTED_APPLICATION_DATA. This doesn't happen with any website owned by Google, such as YouTube, Google Docs, etc. I don’t know if there are any others that it manages to connect to, but those are the observations I've made. What can I do?

I visted a web site once and left after trying to watch a some movies without any success. Now my firefox are sending notification to my deasktop from this website. But the site is no longer opened in my browser. I tried to to run the antivirus but nothing was found. I checked for any extension and nothing as well. The notification are coming from the firefox itself and I dont know why. And I dont know how to stop it.

In seeking a way to reduce the CPU & RAM usage, I read that perhaps turning on the Hardware Acceleration might help. And to do that, you must first de-select the default setting which says FF will use the best settings for my computer. Well, when I opened that section, neither one was checked! So, should I first try the default setting, and if that doesn't help, then try HA? I'd always heard not to use HA, for some reason, but I'm ready for trying anything that might help use less resources, and open webpages more consistently.

Which is the best setting to use, or neither one?

Hi, the site "https://pixabay.com/" is suddently extremely slow with mozilla. The pictures don't showup or take many minutes before you can see them. Normally only white boxes show. The same site (pixabay) with the browser "Opera" works perfectly. I always use mozilla and since a short while it just doesn't work with pixabay (a site for royalty-free images). Can you please fix it? Thanks. Regards Elisabeth

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.
