Firefox Support Forum

Hello, I am changing computers. I used Mozilla Firefox on the old computer and now on the new one. It's the same version; I checked. I exported the bookmarks from the old computer as HTML (that was the only option) but when I try to import them to the new computer and the same version of Firefox, they will not import.

Help?! Thank you so much! Julie

The Aer LIngus website crashed earlier this month, but was reinstated shortly afterwards. But I am still unable to see it on Firefox, though have no problem on Opera. I get a message on Firefox: "To regain access, please make sure that cookies and JavaScript are enabled before reloading the page". But I didn't make make any changes to my Firefox settings so am at a loss. Help! Thanks.

From time to time i need to log into my ISP's website portal, yet from today which is since the update yesterday) it will not allow me to it has my log in details saved correctly, but when i try to log in the sit it says they are incorrect, which they are not.

At first I thought the issue was with my ISP's website, so I was on the phone to them and together we tried crhome and edge and the log ins worked just fine, but not with the Firefox browser.

So sadly either something you changed in that update seems to be messing with the log in on this site and possibly others or possibly one of the add ons I use with it together with the browser is now causing an issue and is interferring I wouldn't have the first clue.

I don't want tabs i open through middle click to be focused immediately. I checked my settings and they aren't supposed to be doing that based on what I see. How do I get this to stop?

When expanding any video to full screen mode, the video does not occupy the entire screen. However, if Firefox itself is in full screen mode, then the video will occupy the full screen.

I tested this on YouTube and another website's video player and was able to consistently replicate the issue.

Hi all; once again and seemingly too often, a Win 10 BSOD and Firefox was reset and where are my bookmarks ? Normally I had them on the LHS of the page but this is getting too much as I cannot find them anymore. Can someone give me a nudge to where I can find them ? rJ

Hello. My Windows 10 suddenly crashed, so I reinstalled on a new hard drive, with the latest version of Firefox. My old Firefox, was completely up to date but still used the Key3.db file for my saved logins, and it will not work with the newest version. I tried creating a new profile and pasting the logins.json and key3.db files, as suggested by an old Firefox KB article, but that doesn't work any more. Is there any way for me to get the saved logins out of the older JSON file with the Key3 file? I desperately need help with this, and would appreciate any that someone could give.

Regards, Brian Mercer.

I have been having issues with the checkout page of my website. My problem was most likely coming from our payment provider causing issues with updates. I switched payment plugins until it gets fixed. (In case you would like to know the extent of my troubleshooting. I ended up installing a brand new wordpress install on a subdomain and the error still occurred.)

This is most likely not related to my initial payment provider issue. When I view issues in the console I keep getting error messages. These issues affect my ability to use the checkout page on my Firefox. We are currently processing payments successfully. These errors do not show up on Chrome.

This is the website page I need help with. https://heartlandforest.org/checkout/

I can't tell if this is happening to everyone or just me. I don't know which resources were blocked or where to fix this. My website and my server do not have a CSP. I have been looking for an answer for over a week before attempting to try asking here. Every issue I have noticed in the past week on my site has been one big red herring after another.

I've tried to search and found some other posts about this, but not a ton... leading me to believe there is something wrong.

Issue: Fonts on some sites are too heavy/bold (vs appearing correctly on Chrome/Chromium browsers) Environment: Windows 10 or 11, Firefox stable (currently 105.0.1) Example site: https://www.subaruoutback.org (this is not the only one, just an example) Workaround(s): I can do one of two things... I can either enforce browser fonts globally, which fixes the issue but then also break some sites in other ways or I can use an add-on to let me selectively enforce browser fonts as needed (which is what I am doing).

Screenshots attached, this is my experience on multiple PCs (Windows 10 and 11). One image is from Firefox, one is from Chrome.

On some sites, it isn't a huge deal... maybe just looks bad but is functionally fine. On some sites the issue is more impactful and actually creates readability issues.

Of course I can continue to work around the issue, but ideally I would like to fix it.

I did read that there are some changes site owners can make for font handling, but obviously requesting that sort of thing isn't realistic in a general sense.

Thank you!

Hi, I'm a very happy long time Firefox user. I use the extension "Dark Background and Light Text" so that my webpages are much more easy on my eyes. The extension works everywhere but in "support.mozilla.org".

How is it possible to have dark theme in Mozilla's support pages too?

Thank you very much. Prayan

Hello, I know when I closed the firefox browser , I can reopen firefox browser and click "settings"-- " history" --" Restore previous session" to retrieve all the webpages I was viewing last time. but this time it seems I made a mistake . I closed the firefox browser in the beginning with many valuable webpage still opened, after I restart the firefox browser, I close the browser by accident without firstly reloading all the restore previous session . Then I have to open firefox brower again, and try to click "settings"-- " history" --" Restore previous session" to try to retrieve all the webpages I was viewing in the first time. but this time no previous session can be loaded. since those webpages I was viewing are important webpage I need to check, May someone tell me how to get those valuable webpage link again? I know I can try to find those webpage link slowly by checking all the history day by day. but honestly speaking, I have 15 around webpages in the firefox brower and some of them are viewed around 20 days or 30 days before . I haven't closed my firefox browser for almost 40 days so it will be very hard for me to search the history webpage to find out them one by one. I am not sure whether there are some tips to try to load the "restore previous session " again for the first firefox browser I closed.

I am able to find the mailto setting easily. However, there are no clients listed to choose from, no gmail, yahoo, nothing. If I click "choose other" I'm expected to choose an application from my computer. I just want to be able to click a mailto link and have it go out through a new tab via my existing, free, yahoo mail account.

As far as I can tell, this has something to do with Firefox aggressively offloading stuff from memory to storage. When I alt-tab at times, Firefox completely freezes. Every Firefox window hangs on a single image and I am unable to interact with anything for a few seconds. During these seconds, I can see the memory % in the Windows Task Manager slowly climbing until Firefox unfreezes itself, so it seems to be loading stuff back into memory. For example, it'll climb from 55% to 70%, taking its sweet sweet time. I also see some disk usage with 'System' during this time.

This behavior occurs even when I'm active on the browser and at 50% memory. It seems to occur more often once I hit the 60% memory mark.

I'm almost certain that this is a Firefox-specific issue, because I can interact with any other program during this period. It is only Firefox that stops dead in its track.

Is there a way to make this behavior less aggressive? I'd rather not have my alt-tabs freeze every few minutes.

While exploring about pages in Firefox, I came across about:profiling. I'm not sure what exactly it does, but since I've been to it, a profiler icon has been added to the toolbar and I can't find any way to get rid of it completely (only ways are to hide it). If it could be added, there must also be a way to remove it? How can I close it?

Just lately I have been finding that, for a few websites, they are unusable because the screen looks extremely blurred. I have attached a screenshot. Compare this with what you see at ba.com.

I am wondering if this is caused by a new secure feature of FF which is incompatible with these few sites. Really, any suggestions would be welcome. Otherwise I have to use Edge..
