Cannot install add-ons error: "Add-on could not be installed because Firefox could not modify the needed file"

I've run into a troublesome error with Firefox for probably eight months now, so I have not been using the browser. Whenever I attempt to install ANY add-on from the Firefox add-ons page, I get the message "[Add-on name] could not be installed because Firefox could not modify the needed file". Furthermore, attempting to download the add-on file manually (should it be available on a github page or the like) leads to the same message or a notification that the download failed.

As a matter of fact, downloading almost any kind of file on Firefox inevitably fails. The exact notification is shown in the upper-right corner of the browser window, where downloads are shown, and beneath the file in question is an indicator that says "Failed". Everything from .png to .zip to .exe appears in the downloads queue for a second, then fails.

I have tried every solution the Firefox add-on troubleshooting page has suggested, including solutions suggested in other threads, such as deleting/creating new profiles. I have also attempted to completely reinstall Firefox on multiple occasions, as well as the refresh Firefox option.

To recount, the following troubleshoot solutions did not work:

--Everything on the Firefox add-on troubleshooting page --Restart Firefox --Refresh Firefox --Create new Firefox profile and attempt to install add-ons from there --Delete and renew the extensions* files from the profile root folder --Modifying the xpinstall.signatures.required in about:config (true or false, doesn't matter) --Modifying the extensions.alwaysUnpack in about:config (again, true or false, doesn't matter) --Double-checking allow list and permissions on local firewall and antivirus software (the app is protected, add-ons are allowed) --Disabling antivirus software --Running Firefox as Administrator --Reinstall Firefox --Restarting PC

If I want to download a file or add an extension, I need to switch to a different browser such as a chromium-based one or Microsoft Edge to download the file. In the case of add-ons, I switch browsers, download the file, and select the "install add-on from file" option under "manage extensions" in about:addons.

One final thing. It seems that sometimes streaming sites won't work on Firefox (even with ad-blocker disabled or the site allowed through the ad-blocker), and sometimes video won't properly load either. These things work fine on other browsers.

I really like Firefox as a browser and enjoy the privacy it provides built-in. I didn't have any of these issues up until last year and I was forced to switch over. I would really appreciate any help with this.

Despite trying to disable https mode, Firefox will not allow ordinary http sites to load. Consequently I can't access most of the Australian Bureau of Meteorology (bom.gov.au) pages or any other websites that don't use the extra 's' but are still secure. Mozilla suggested switching from Strict back to Standard but I still can't access ordinary http sites. Can anyone help, please?

I am using Arlo security cameras which store the video captures as MP4 files. The Arlo app has video playback feature that works in Chrome or Edge but does not work in FireFox. From what I have been abe to glean from searches, Arlo uses HEVC Codec that FireFox either isn't compatible with or is lacking the codec. Any suggestions?

Hello, I have two websites that I've designed with cursive fonts in some headers. Whereas they display in other browsers, they do not display in Firefox. I asked this question years ago, and to date, no one has provided an answer.

Not only do the headers not display the cursive font: savoye let and allura, what they show are enlarged and bold letters that completely destroy the design. Surely, there is a reason for this.

Here is one of the sites (the other is still in design mode): https://summitlighthousephoenix.org

I recently noticed that in the settings it says "Your browser is being managed by your organisation". The certificate "ImportEnterpriseRoots" seems to be affected. I have seen guides saying to delete a registry key but I do not have a Mozilla folder in my policies.

It is worth noting I do run two anti virus software. Kaspersky total security and gridinsoft anti malware. Just wondering if there is a way to permanently remove this or if its just a side affect of my anti virus software.

Thanks

With the last update I suddenly have the url/search box background and its search results drop down background set to an ugly pink with diagonal lines.

I am visually impaired and now its almost impossible to use firefox because I can't read the text on top of the diagonal colored bands. There doesn't seem to be any settings to turn on or off this appearance.

I will have to switch browsers until this is fixed and I don't want to.

Since the update before the most recent one, web pages of major sites are not loading properly in Firefox on Mac laptop. Cannot load Hulu, MSN News, Booking.com, but they work fine on Chrome. I've used Firefox since its inception and I hate using Chrome, but it looks like I am going to have to, as I cannot get any response or support from Firefox. Is there any hope at all or should I just get used to Chrome? This is my second post--I attached screen shots to the first one, but no response, so I'm thinking they have no fix.
