I-Firefox Isithangami Sokwesekwa

• The attached image shows Firefox (on the right) not displaying Helvetica correctly. It appears jagged and not pleasant to look at. The browser on the left is Edge and all Chromium based web browsers seem to render it as it should.
• I've tried to look into (about:preferences#general) and the option that says (Allow pages to choose their own fonts, instead of your selections above) is ticked.
• I've also tried reinstalling the browser, clearing the website cache and also, removing my profile from it. None of these seemed to fix the issue.
• It's been persistent for quite some time now, however I didn't really find any articles regarding this issue.

  Any help would be greatly appreciated!

I Been Hacked Need Hacker has control of everything.

I am trying to visit this website TPLinkLogin https://tplinkloginz.xyz/ through Mozilla firefox on my Windows computer. But I am not being able to open it. Although, the website works fine with other browsers like Edge.

I have installed Mozilla and I been using my website in it but now website https://technicalgang.com/ isn't opening in this browser even I cleared its cache and browsing history etc I have attached screenshot below you can check, kindly help me. Thanks!

How fix this. Have googled the problem and tried all proffered solutions. No change. Others seem to have had similar problem, mentioning certificates, but got no help from Mozilla, that I saw. I have put the little jigsaw icon o the search bar, to no avail. Am deadended.

The latest update has resulted in an error message: Platform version 84.0.1 is incompatible min version >= 84.0.1 and max version <= 84.0.1 Can this computer no longer use Firefox?

On my Youtube tab when i try to search or write a comment, everytime I end up pressing a shortcut button such as the spacebar it stops and starts the video and when i try to use the M button it mutes and unmutes then video et., even thou i try to write a sentence. I have refreshed, updated my windows and browsers etc, cleared my Cashe. Other Browsers are fine only on Firefox. Have not had that issue before.

I had to clear History and Cookies on my desktop to get an online purchase done. I was able to add my passwords for every site bar one (afl.com.au). It just won't accept my password despite changing it. Works fine in Brave and Chrome. Also fine on my laptop (didn't clear anything there). Any help sincerely appreciated.

REALLY dislike shortcuts, using the keyboard which require multiple steps and keystrokes where as the "+" was one key stroke to do simple tasks like ADDING A NEW TAB

I just logged on and went to Netflix. I was logged in under an account I haven't used in a year. While trouble shooting the issue I discovered the browser updated and synced my old account with my new one. This included passwords and logins that were compromised in data breaches. I don't even use the old computer or any of those passwords. Now I can't even get Netflix to play on there with the correct login data. I took that old account info out and deleted the cookies from compromised accounts. Can anyone tell me how to fix the sites, other than switching away from Firefox entirely?

I am not happy and can't even leave feedback to get real support from the people who did this dumb stunt without even asking me first.
