Diễn đàn hỗ trợ Firefox

Hi, the turbotax website forced me to update Firefox and since I did, I am no longer able to open the browser at all. The error message reads, "You can't use this version of the application "Firefox" with this version of OS X. You have OS X 10.11.6. The application requires OS X 10.12 or later." Unfortunately, from what I have read, I can't get that update that on my iMac (21.5inch, late 2009) OS X El Capitan Version 10.11.6. Is there any way to downgrade the Firefox install? I can't even see what previous version of Firefox I had before because I can't open the browser anymore. If anyone can help I would be super grateful. Thanks in advance!

Hi,

My computer was on during the week-end and when I came back home I noticed we had a couple of power outages. Computer restarted automatically (Win 10 22h2) and when I launched Firefox, it started as brand new with all my addons gone and none of the previous session restored (I had 4 Firefox browsers opened with each 20+ tabs opened).

I have tried looking at C:\Users\MYUSER\AppData\Roaming\Mozilla\Firefox\Profiles but found nothing of interest. Where is everything and how can I restore everything I had ?

I even tried Troubleshooting mode and downgrading to a former version of Firefox (126.0.1 64 bits).

Thanks,

Hi everyone,

I run an online barber supply store called Magnus Supply (https://magnussupply.com/) where we offer a variety of products including clippers, trimmers, shavers, grooming products, accessories, and sanitation supplies. I'm always looking for ways to improve the user experience on our website and streamline our e-commerce operations.

Can anyone recommend browser extensions that could help with:

Enhancing website performance and speed. Improving user engagement and retention. Simplifying the checkout process. Better tracking and analyzing customer behavior. Ensuring data security and privacy for our customers. I’m particularly interested in extensions that work well with Firefox, but suggestions for other browsers are also welcome. Your insights and experiences would be greatly appreciated!

Thank you in advance!

I want replace firefox Windows Mozilla MSIX 1- 0 package browser from ms store with regular downloaded version but I do not want to lose all my settings.

How do I go about this?

Thank you!

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.
