Running Sonoma 14.4.1

Safari and Chrome work as expected.

Upon startup, top email displayed is the 2nd email present in the inbox. If 1st email is one at top when leaving TB, next startup will show the 2nd email on top. You can then scroll up and see the top one. Likewise, if a new email come in, it also shows the one below that as the top one and must scroll up to see it. No emails are lost, just a display thing. Don't recall which version this started, but it didn't use to do this.

TB 115.11.0 (64-bit) Supernova, Windows 10 22h2

I have been using Firefox for many years and never had issues. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I cannot even delete email from my Gmail! It's piling up. Downloading can take over an hour! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went back into "About:profile"s and created a new profile. It it did not make any difference. I also did a Firefox refresh. Did not help any. I went back into the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have three extensions in Firefox. I don't know what else I can do to fix this. Also, my drivers and other software are automatically updated by Windows. My HP is only 2 years old as well. Everything was fine in Firefox until that XUL error message popped up and I had to uninstall and reinstall Firefox. That is when everything became agonizingly slow!

Update: My computer is barely usable anymore because of the Firefox issue. Having to wait for a minute or more for everything I do on the internet? I know it cannot be my computer itself because it is not even two years old yet. I may have to dump Firefox if I cannot get this fixed. I have Norton 360 and it is not malware or a virus. Firefox messed something up.

whenever I am filling out an online form that requires basic info, Firefox prompts the common info that I have input in the past via the Auto-fill feature. Whenever I click on the suggested information, a new settings tab opens and switches my screen view to that tab. This didn't happen prior to the most recent update and has made filling out various forms extremely tedious and frustrating.

I have a fresh install of firefox on a fresh install of windows 11. I am trying to login to my dropbox account and when I get to the MFA page the "Continue" button does nothing.

There are no add-ins installed in firefox and I tried it in safe mode as well. I turned off enhanced tracking protection. The site works fine in firefox on another machine. It works in other browsers on the same machine.

Dropbox support seems to be unwilling to help, they just told me to use a different browser.

We use a firewall that doesn't support the ZSTD standard yet so I need the ability to turn it off on the Firefox browser. I haven't figured out how to do that yet since the new version came out with support for it this week. (We have turned it off for Chrome based browsers already.) It tends to break a few of hte websites we are using.

Thanks.

Since last "update" of Firefox for Windows v126.0

I can no longer access Gmail

keep getting this Error code: PR_END_OF_FILE_ERROR

can access my Gmail account on my phone using Firefox for iOS but not the laptop, what changed with the Firefox 126 update? what am I missing?

So I been using Firefox forever until February when I noticed that all my saved passwords were not available and I had to sign on to my account every-time I brought my laptop up. I tried everything i could think off or read but nothing works. I do shutdown my computer using Glary but I have turn off all cleaning of Firefox. I want to go back to Firefox but can't seem to get past signing on every-time to my account to get full access. Any thoughts on what I need to do?

I'm having problems with the Cardbook add-on but it is up to date based on my version of TB. When I go into Preferences->Advanced-> Update 'Check for Updates' shows I'm up to date. However, when I check archived versions it looks like the last version that worked with a MAC release of less than 10.12 is 78.14.0.

I'm confused if I can upgrade to 78.14 and how I would do it?

Thanks for any advice

P.S. and yes, it's a very old Macbook from 2009.

I've used Thunderbird for many years and occasionally a message I've sent takes ages being saved, then finally it isn't. This has become more frequent recently together with having to re-enter my email password. I use Ubuntu (22.04.4 LTS) so I don't use anti-virus software and I don't use other email clients (only Thunderbird 115.10.1 64 bit).

I sometimes briefly lose my internet connection, though seemingly not when the email malfunctions, so could my old BT hub be the source of the problems? In the absence of any other solution maybe it's time to get a Chromebook and see if that's any better with Thunderbird. Firefox also now freezes a couple of times a week (and not being an IT wizard I hate not knowing what incantations to type into the terminal when anything goes wrong.)

I found a file that has an IP address at the top of it. And the IP address is from China. recently my email address showed up on dark web. Do you think It could be connected. and is hack?

Nuance Dragon 15, my speech to text software, periodically opens a window and says restore privileges to the Dragon web extension for Firefox to improve performance. However, the fix it button is inactive and Firefox has never seemed to have heard of this web extension and denies all knowledge of it so the cycle continues. Has anyone else encountered this novel issue, please?

External request to provide email content and send automatically, such as HTTP GET or POST similar to restAPI to do stuff on thunderbirds application for automated tasks, like opening emails, send email.

Almost consistently every day and often multiple times a day, Firefox will freeze up, unable to load new tabs, and sometimes will display a message that the browser has updated and requires a restart. Upon restart (when fozen), I'm prompted to create a new profile because I'm using an 'older version of Firefox'. After creating a new profile, I'm able to update the browser and switch back to my original profile.

Although this is a relatively easy fix, Firefox requiring me to restart my browser without being able to do anything else is disruptive alone, but not even completing the auto updates, crashing, and requiring me to do a workaround just to keep using the browser is driving me back to a more stable browser.

I don't remember updates requiring a restart before, or maybe they didn't happen enough to cause issues in my workflow.

I have tried using the 'restore' feature in the uninstaller hoping that it might resolve the issue with no results, but I haven't found any reasonable other options with my searches online.

When I view emails with photos attached inline (both in preview pane and fully opened) i can't see the images as they are massive and go way off the screen. Is there a setting to provide some kind of sensible default so the images are sized within the email i am looking at, so i can view them without downloading and opening in a photo viewer? thanks
