Firefox supportforum

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

I have chosen to not auto-update the browser because it interferes with my work. The precise setting is called "Allow Firefox to" "Check for updates but let you choose to install them" (screenshot attached). However, this setting is not honoured. Every month, the browser auto-updates and forces a browser restart for me to continue working (screenshot attached). For 126->127, there was in fact no notification to update and the update happened automatically in the background with a restart forced upon me. What's the point of having this setting if it's not going to be honoured?

Dear fellows,

I did lost all history data after a previous update, my user got corrupted data and somehow I did manage to import the info into Edge browser. To my surprise after I reinstalled a clean Firefox, it only imported back 3 months of browsing history. Topically, average user keep a computer 3-4 years.. I don't know from where developers came with the idea of limiting to such a shot interval. I have thousands of browsing history links from more that 10 years kept and I need them all.

Tried to increase the number from about:config, but there is an option only for Chrome which I never used and always hate :)

I did installed Chrome to convince myself about it's ingenuity, even if it was not necessary. It does have import option only from Microsoft Explorer, no Edge.

If there is a solution for importing a longer period and high number of entries, please share it.

I'm not an IT expert, but I can manage consoles if there is an even deeper option to modify config files.

Thank you in advance!

Firefox Installer.exe starts and, after some time, gives that error message: Ihr Profil "Firefox" kann nicht geladen werden. Es ist möglicherweise nicht vorhanden oder ein Zugriff ist nicht möglich.

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

hello,when i download my attached files in mailbox(mail.xmvds.com), it can be everytime warnning me ,but i trust this url ,it is my company's office mailbox ,how can it unblock it ,?

As title- Cannot download for example webm format, but jpg is okay. cannot install any addon, theme or anything. DRM didnt install as well. i was trying reinstall, refreshing browser, rebooting.

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.
