Dark Mode used to work beautifully in Firefox. Today it stopped working. I can choose Dark Mode in the settings page, and the settings page itself then uses Dark Mode. But Dark Mode does not work in any of the other pages, only the settings page. I think it must be a flaw in an update that was installed automatically today. (September 7, 2021)

Is there a way to uninstall this update and go back to the previous version. Dark Mode used to work beautifully and Firefox was my favorite browser. Can someone help? Thanks.

Why can a stupid failing script on a web-page, or even intentionally so programmed script disable the copy (and sometimes paste) functionality?

How can this be disabled/fixed?

One highlights a text (any text) on some web sites, Edit menu allows Copy, context menu allows Copy, one hits Copy, nothing happens. It's not even a page where someone wanted to "copy protect" some information.

Copy and Paste should work just as advertised since those were invented, how hard can it be to get that right? Even stupid Notepad never fails at it. And no, I don't care what the idiot who programmed a page though would be/should be best for me, I want Copy to be copy, Paste to be paste. This used to work in "original" Firefoxes even when page developers wanted to make it not work.

And yes, while on a given page Copy fails miserably, at the same time in other pages it works.

Error NS_ERROR_NET_INADEQUATE_SECURITY on every page

Hi, I've been having issues with Firefox for some time now. Every page I got to throws a NS_ERROR_NET_INADEQUATE_SECURITY error. I cannot fix it by setting network.http.spdy.enabled.http2 to false is because Firefox then starts crashing. In the past I've gone around the error by turning http2 off, but recently, first the developer edition, then after today's update to 91.0-0.1 of stable version Firefox crashes if I turn the feature off.

The developer Edition started throwing NS_ERROR_NET_INADEQUATE_SECURITY sometime in spring, then started crashing in June I think. The stable version followed soon as described above.

I am submitting this ticket from a beta version, which for some reason does not have this issue.

I thought it may be the Linux version of Eset, but removing it did not help. I cannot think of any other reason why am I getting those errors, but it seems I am alone because my colleagues don't seem to have this issue neither on macOS, nor Windows.

How can I permanently force firefox's automatic updates to be turned off? Which guy modified the original design for the new version of Firefox bookmarks? Is there something wrong with that man's brain? Is the spacing of the new bookmark item too large to read? It's very uncomfortable.

I just installed the latest Version of Firefox 101.0 for Windows 10. Then when I tried to download a pdf file from my yahoo mail I received the following message: "Problem loading page" Firefox Can’t Open This Page To protect your security, dl-mail.ymail.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window. Learn more… Open Site in New Window Report errors like this to help Mozilla identify and block malicious sites

So, in order to open the page I have to press "Open Site in New Window"

Please advice why happened this issue and how can be fixed.

How do I change the font size of Firefox's headers elements: menu, tabs, bookmark toolbar, bookmark manager without changing the font across Mac iOS or otherwise messing up the other settings?

I've searched this question and found one answer archived that did not really fix the problem. I'm looking for an extension or a setting integrated in FF, not a font size change in Mac iOS (Monterey) or one that changes the font in the browser pages.

Love FF and Mozilla and all the volunteers who make my entire work day so easy with great, secure, handsome products! I'm a devoted fan. Thank you!

I have two versions of Firefox installed on my work PC, the regular one for my everyday browsing and the Developer's Edition for my work with the regular one being my default browser. For some reason, through no effort on my part, I ended up on the beta channel for the regular browser.

That was OK until the latest beta (version 90) started showing an extremely annoying bug. On a daily basis, on average, it will stop loading pages for no reason. For that reason, I'd like to get off of the beta channel and get back to using the release version. Would uninstalling the beta version and installing the release version do that for me? Or will I somehow end up back on the beta channel and get upgraded to the beta version again? (If I do have to uninstall the beta and install the release, I want to keep all of the settings, bookmarks, plugins, etc. that I have in that browser. I have the Dev Edition browser set up to never sync, so it has a different set of settings, etc., which I don't want carried over to the other browser.)

Good day.

My use case is the following. I use Firefox Developer Edition for developing websites. Usually the development happens on a certain part of the page. Most of the times it is not on the top of the page, so you have to scroll down to it.

Sometimes when the page is refreshed a jump to the top happens. So then I need to scroll down again. It takes a lot of time and concentration away if it happens dozens of times a day.

It often happens after I did some changes to the files on the page. It usually does not happen when I refresh the page a couple of times (when I purpously want to reproduce this problem).

I did try running Firefox in Safe mode, but it didn't help.

What can be done to fix this problem on my side? Is this a bug in Firefox itself?

Since Firefox 89 (maybe one or two releases before) *.localhost sites are not accessible, but those sites are available through other browsers or tools (Postman, Chrome, and Edge). Localhost is an Nginx server mounted on WSL2, so it’s IP does not correspond to 127.0.0.1 which is what Firefox thinks (about:networking#dnslookuptool).

There is no Proxy enabled. I also deleted the site settings on Firefox, disabled IPv6 and prefetch with no result.

I can't open or create facebook accounts with any browser. Why? Even as soon as creating a new facebook account and nothing is posted, I am not obey their community rules. I do nothing strange and peculiar things. For example, First Name: Myo Last Name:Tun DOB:28/12/1978

Nothing is out of facebook community standard. But I can't use facebook with any browser. Why?

With respect, Myo Min Tun, Myanmar.
