AdBlock Plus extension does not work after updating Firefox (to version 102.3.Oesr) on desktop MacPro. Deleting the preference file (pref.js) has made no difference.

This problem has not occurred after updating Firefox on my laptop Mac Book Pro.

Both computer use OS High Sierra (10.13.6).

Please advise. Thank you.

So, the system requirements system requirements for Firefox 108.x desktop only mention macOS 10.12 (High Sierra) through macOS 12 (Monterey)

Is Firefox lacking support for the latest version of macOS 13 (macOS Ventura?)

I started using Firefox ESR a while ago when I had an older version of Mac OS. Now I am running High Sierra (OS 10.13) and I think I could use the standard release of Firefox, which may have newer features supported. How do I switch to that?

i have had to reformat my imac and reload firefox how do i use the search box in the centre of my home page and not the one in the tool bar. every time i type in the box it transfers to the tool bar. my home page search box has no arrow or spy glass at the end of it how do i get it to work again

I am using an iMac that uses MacOS High Sierra version 10.13.6. Because of its age, it cannot use an operating system beyond High Sierra. When I selected to update Firefox today, Apple generated a message that said Firefox would no longer work on my computer. Firefox 102.14 Oesr (64-bit) is installed and seems to work.

Will I no longer be able to update Firefox?

I am getting SO tired of being told to stop or close the page THAT I AM USING to speed up my browser. How is that going to help anything? If I stop the page that I am USING, then I cannot do what I want to do. How about you stop cramming in so much garbage that the browser cannot run properly?

And, yes, I know...this is an obsolete computer....so what?

I think I accidentally changed the proxy settings on Firefox for Mac V. 106.0.1. I get an error message with most websites now, including all Google sites, stating

"Secure Connection Failed. An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR. The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem." Please advise..

Even when I'm in Full Screen mode on my Mac, Firefox insists on putting a tab bar at the top of the page; how do I hide that tab bar? I've searched all over the settings and Internet to find an answer, but no luck in finding the answer.

The main idea of "Full Screen Mode" is to maximize the usable display area of the browser window. When I'm using Full Screen Mode, I am intentionally using just one URL. If I need a new window, then I'll get another Full Screen Firefox window (not a tab). This is an incredible waste of screen real estate, to have a single tab consuming an entire row... so irritating!

Firefox didn't used to do this; can you tell which older version that I can use that doesn't have this behavior?

Thanks...
