I-Firefox Isithangami Sokwesekwa

My Linux/Computer guru passed away 5 years ago I have been using Firefox Quantum 57. 0.4 64 bit for Linux Mint 1.0 but am finding sites I need to access won't open or if they open can't use the functions there. I know nothing about computers and I have not been able to find a tech to take my desktop to to get it updated. I am afraid to update because computer is currently set up with protections so I can do banking etc.. but soon I won't be able to access that. Any suggestions as to what to do at this point or suggestions of tech's in the Far West Valley of Phoenix AZ to assist ? Thanks so much for your time and any suggestions. Cheers,

When I open emails many times the letters are gibberish. The letters are changed into symbols and weird looking letters. Sometimes closing Firefox and reopening helps, but usually I have to restart my computer. Even then, it may or may not be readable. Some emails are only partially this way, but most are complete gibberish. Has been happening for a few months. I have updated Firefox and am running the newest update. I am using Microsoft 365 email. Other computers in the same office do not have this issue. Any ideas how to fix this?

When I open the Google "Choose an account" page, my account name doesn't show up above my email address. The problem ceases only temporarily when I clear the cache and the Google cookies. Any suggestions?

Recently , I would say within the last month or so, all the sudden when a site asks for my username and password I cannot use autofill. With Firefox as the auto fill provider or a 3rd part tool password program like Biwarden. For a while this worked like a charm but what happens is this username and password fields come up on a webpage. At the bottom I see firefoxes prompt and Bitwardens prompt to select a username. I can do this in both but when I click on the username nothing happens. I have uninstalled both and reinstalled made each a provider etc... This does not happen with Chrome

This feature and this feature alone has me thinking of just leaving Firefox first the revamp with mobile. Got used to it, now this, sorry but this is a deal breaker.

I am using a OnePlus n10 5g on Metro. Updated as updated can get I am at a loss here but auto fill has be ome useless in Firefox.

Any ideas???

I have firefox version 113.0.1 on two computers both running windows 10 Pro. the last update failed on both computers and firefox would not run so I reinstalled version 113.0.1 Any suggestions?

Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz 2.40 GHz 8.00 GB RAM

Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz 3.30 GHz 16.0 GB RAM

New version produces "Access Denied" when logging into Chewy.com Please fix this. I tried to add an image, but, like last time, doing so froze the page and I couldn't get back here. Had to start over. Can I revert to the earlier version of Firefox that worked? If so, how?

The YouTube videos load in troubleshoot mode, so I reopened Firefox and disabled all extensions. That did not help, so I uninstall all extensions. That does not work either. Other browsers work, but Firefox does not.

In a simple HTML file containing an Arabic / Urdu / Persian phrase: "با نشئہ درویشی در ساز و دمادم زن", Firefox in Linux (Ubuntu, to be more precise) uses the default font (DejaVu Sans) for the whole phrase except for one character (UNICODE: 6C1). Font used for this character is Noto Sans Arabic UI. So the text looks broken due to different fonts.

Please have a look at the attached screenshots for better understanding.

I've tried to search but could not find how exactly Firefox resolves preferences in Font Settings and CSS "font-family" preference to local fonts in Linux. Does this have to do something with "fontconfig"?

How can I make Firefox use only the default font for the whole phrase?
