I would like to use HTTPS to access my router's web interface without having to bypass the "Warning: Potential Security Risk Ahead" page.

Following my router's instructions I exported the certificate. I then accessed the Privacy & Security settings in Preferences, and under View Certificates I imported the router's certificate.

When opening the HTTPS web interface Firefox reports SEC_ERROR_INADEQUATE_KEY_USAGE.

I occasionally visited this site https://referti-empoli.uslcentro.toscana.it/portalepaziente_user/user-login (it's a site managed by the local health authorities). I am reported that a safe connection cannot be established with the message PR_END_OF_FILE_ERROR. I am not shown any option to consider this site SAFE (no matter what, it's SAFE and I need to access it occasionally). I also use ESET anti-virus software. I can access through other browser, at least the show me it couldn't be safe but allow me to go on. I don't want to switch browser once in a while to navigate. I want to use Firefox in any case (or switch to another one that allows me to). How can I make it work (apart from deleting cache, temp files and history, which did not work)? Thank you.

Whenever I have to scan a qr code, It turns into whatever that is in the image attached. Same thing happens sometimes when I try uploading images on certain websites. It works fine on other browsers. It also happens while using Firefox safe mode. Sorry for not being detailed enough.

I want to transfer the profile from an old PC running Windows 7 to a new PC running Windows 10. I've copied the old profile to a USB stick. After much searching I've found the profile created by the new installation, but it seems to appear in two folders: AppData/Roaming/Mozilla/Firefox/Profiles, and AppData/Local/Mozilla/Firefox/Profiles. Should I simply substitute the old profile for both instances of the new profile? NB This message is posted from a different platform (Mac) Thanks

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

Firefox 78.0.1 does not remove closed pages from memory - lags and high RAM usage

After updating from 77 (I think it was 77.0.2?) to 78.0.1 I started noticing terrible firefox performance after a few minutes of browsing. My standard browsing habit consists of launching browser with 1 pinned tab and 1 home page (so 2 tabs only), then opening 5-10 tabs from my bookmarks, checking pages then closing them and leaving only 1 pinned page open. In firefox 78.0.1 after doing this (opening and then closing multiple tabs "to the right" using new context menu added in 78) my ram usage does not drop. It goes from 2.4GB (system only usage) to 5.0GB and does not drop after closing tabs. However when I open 10-20 tabs again RAM usage does not rise (maybe slightly, like 5.3GB). So it looks like firefox has multiple tabs stored in ram and opening new tabs just rewrites that memory instead of allocating new one. I have 8GB of ram so 3GB of usage from 1 open tab is crazy. I think it was 500-900MB before. I also have terrible lags because of this - browser hangs up every few seconds for few seconds. I had trouble writing this post with 2 tabs open because of 3.3GB ram usage! Restarting browser helps - ram uasge rises from 2.4GB to 3.2GB only (800MB for 2 tabs) but every new opened and closed tab seems to stay in memory. For example if I open 10 more tabs except for 2 that always open so I have 12 tabs I have 3.6GB memory usage. After I close them it slowly drops to 3.5GB instead of returning to 3.2GB. It does not matter how I close tabs - using right click context menu (close other tabs, close tabs to the right), using X on tabs, or using add-on to close all tabs except for pinned ones. They always remain in memory somehow. PLS fix this ASAP.

P.S. I also tried checking about:performance menu but there is nothing interesting here. It says that 2 opened tabs and addons use 100MB of memory which is not true because browser at this moment uses 1060MB.

Update 1: I also tested safe mode. 3,4GB of PC RAM usage on firefox safe mode start. Opened few tabs, ram usage goes to 4.2GB. After closing all tabs except for 1 ram usage start to SLOWLY decrease but it stops at 3,7GB. Ram usage drop was really slow like 10-30 seconds. It should be instant after closing tabs.

Since the latest updates, I can't access at least two sites I need to go to daily. (chase.com and constantcontact.com) All other sites open fine and those two open in Chrome. I read that this is a known issue with the update. I don't understand the fixes. I just need things to work!

I have a mac with a free Avaast app running. Not aware of any firewalls.

Error says: "The connection has timed out" in both cases.

I am on a macbook pro running Big Sur and I do have a time machine backup of that last session — can I get back those open tabs and browser history from my time machine? Can I do it a la carte or do I need to wipe my whole computer and restore from there? Thanks in advance for your thoughts, Sam

I have firefox 82.0.3 and videos on reddit are not loading, well embeded youtube ones are, just not the ones hosted by reddit I believe. The screen just stays blank. I tried this from old.reddit.com as well as www.reddit.com. before anyone says its a setting or an extension, I was doing a clean install of ubuntu and loaded firefox. no extensions, just the default settings. I installed brave browser and it works in brave just fine.

I also have linux mint with firefox 77.0.1 on another computer and it works fine (and that computer has a bunch of extentions as well as a bunch of privacy tweaks in the about:config (the ones listed on privacytools.io)

I also loaded firefox in safe mode and deleted the prefs.js file. none of that worked. I also changed the preference to load play video play audio. didnt work. It seems also gyfycat videos load too.

any suggestions?

Hello, Firefox seems to be using my system's High Contrast text color to render websites. My High Contrast text color is a light grey, to contrast with a dark system background. However, many webpages on the internet have light backgrounds, so when Firefox uses this color, I can't read the text. I already have Options>Language and Appearance>Colors>Override the colors specified by the page set to "Never." This also occurs in a brand new profile with 0 extensions or addons in Safe Mode. I just want Firefox to display webpages "normally", i.e. with black text, without regard to the current system colors.

To reproduce: - Turn on High Contrast - Visit a site such as http://hyperphysics.phy-astr.gsu.edu/hbase/ppois.html - Change system High Contrast text color to any color you wish - Notice that the text on the page also changes to the same color, even with the setting on "Never"

Is there any way I can get Firefox to ignore the system's text color settings? Chrome renders the webpage just fine with black text.

cannot log in to my Bank of Montreal online banking!!!

I've used Firefox for years, and for years I daily do my online banking.

Now all of a sudden, without any warning I cannot log into my bank account. I've tried clearing history, etc. I've tried the about:config change...

I can log in fine with Microsoft Edge.

My wife uses Firefox and she can log into the bank. I suspect that is because Firefox has not updated on her computer.

This is maddening, to put it mildly.
