Using firefox, my page will involuntarily changes size or will highlight text not requested.

If I need to change a setting...pleae send instructions to: mcmkb42@yahoo.ca

i installed the latest version from the website, and it only opens for a split second before it crashes. no error message, it just closes before its even fully open. same thing in troubleshoot mode: the troubleshoot mode popup only appears for a second, i dont even have time to read it before it closes. no error message. i tried a clean reinstall and nothing changed. i opened it in safe mode and it worked with no problems. i read that there are sometimes issues with avast, which i used to have, so i deleted the residual files i found in AppData and Program Files. still nothing. now the only antivirus/firewall software i have is windows defender (and i know that because windows defender keeps telling me haha), and i tried adjusting the windows firewall- still nothing. i would love to include a crash report ID, but there are no crash reports in the folder (photo attached), even though ive tried to open the app half a dozen times since reinstalling.

not sure if its relevant, but just in case- when i couldnt open the version from the website, i tried installing it from the microsoft store, and it actually worked fine at first. but shortly after i finished setting it up (it was probably open for less than an hour), it crashed and then it was the same- crashing immediately upon startup. i have since uninstalled it, in case they were interacting in a weird way, so now i only have the version from the website. i also have the mobile app on my phone and it works like a charm.

i consider myself pretty good at troubleshooting, but im completely stumped here. sorry for the long post, any guidance would be greatly appreciated

Firstly, when I open a second Firefox browser window, it doesn't show any pinned tabs, and secondly, if I close the window without the pinned tabs last and then reopen Firefox, the pinned tabs are gone.

That's very annoying. Do you have a solution for this? Am I making mistakes in the settings?

Thanks for an early reply on this. Best regards Stefan

Even though I have the settings correct in the browser ('Open previous tabs and windows' checked under Startup in the General settings section), Firefox suddenly stopped doing this. I went to help and have tried everything suggested (for example, in this article -> https://support.mozilla.org/en-US/questions/1365225) to no avail. I generally have to have at least a dozen tabs open at a time due to the nature of my work and it is time-consuming and frustrating to have to re-open the every time.

I have tried the 'restore previous session' under the History menu but that is not an option given. So that isn't working for me either. 'Recently closed tabs' is an option but is greyed out / doesn't work.

It is possible that this is a result of a recent update as Firefox has been almost daily been asking me to update. But I do not know how to go 'back' to last version if that is the case ... or how to turn off the annoying update messages.

So what is going on?

Thank you in advance.

I subscribe to a website called flat.io. It's a site where I can enter music notation and get playback through emulated instruments.

I want to connect my Yamaha MX88 music keyboard directly to flat.io in order to have the site software record my music keyboard keystrokes instead of entering music notes by hand. flat.io tells that you are compatible, but I need to change settings to allow midi.

I hope you can help me. Thanks, Jim Whited

When I try to logon to Dropbox I get this message: "Your browser appears to be blocking dropboxcaptcha.com, which is required for authentication. To resolve this issue, please update any anti-virus or ad-blocking software settings to allow connections to dropboxcaptcha.com."

Where and what should I add to get this sorted? Thanks Mo

Hello, One of my customers reported the following message when attempting to view an email in FF browser:

“Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to go.planmember.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.”

Here's the link: https://pages.planmember.com/index.php/email/emailWebview?md_id=40957

We haven't seen any reports from IE, Chrome or Safari.

Any clues as to why?

Firefox stopped working on my laptop after I uninstalled office365. I have reinstalled office, but firefox still not working. It is working on my phone and an old laptop. What are my options? Nothing happens wen I click on the 3 bars, history, settings, etc. Need help, thanks.

I have a 2nd laptop that I need to sync for my passwords and bookmarks, everytime I try to sync it says incorrect password, when I know it's correct. then locks me out after a few attempts but it works fine on the main laptop! Please, I need help! thank you

I have Adblocker Ultimate as an add-on. But I can't seem to put it in my toolbar. I have searched the internet to resolve this problem and nothing worked. It is listed in my Add-ons manager but I can't get it to show up in any bookmarks or the toolbar. It does work but I can't find it anywhere.

Password synchronization is turned on, and I can't see the synced password on the other machine, but I can see the synced bookmarks。As shown in the image, password synchronization is turned on。Hope to get help, thank you all.

I've been to several websites in the last couple of days that won't load in firefox, but will in chrome ( which I had to download to order groceries and I am not super happy about it ). the most egregious was today, I tried to order groceries from a major grocery store: meijer.com and the main page opened but if I like searched for "coke" it would freeze and nothing would load. not just coke, but also any other search term

With Windows 10 autofill with Firefox never worked for me even though the appropriate options were checked. I recently upgraded to Windows 11 and it worked! So happy. But that was only for about 2 weeks. And then a couple of days ago it stopped working. (Maybe from a Firefox update??) It's really frustrating and tedious even with the passwords being filled automatically when I start the login process with the user name. Is there anything that can be done?

I installed the Mail Link Enhancer add-on. It works, sort-of. The subject line and other fields included after the ? in the mailto address do not get filled in. Looking at the add-on info, the developer is Nick, but there is no contact info in the More Information section of the add-on profile. The add-on hasn't been updated since 2020, so I'm fairly certain that things changed since then and that's why it isn't working, but I'm no expert.
