Firefox Support Forum

Firefox browser no longer on W7 laptop. Followed instructions-downloaded setup and installer. Neither will do anything - message says no program association to implement thses files. Help!

I'm running the latest version of Sonoma, and Mozzila / firefox was just upgraded. Once I upgraded to Sonoma I began to notice that command n would not open a new window "sometimes" - none of the dropdown from the status bar worked - except "firefox" - I can drop that down with mouse and click on "setting" which seems to "wake it up" and it functions normally. It just can't wake up if it moves to running in the background, tab applications over to firefox and then command n to open a new window - Anyone else experience this - I can't find a setting?

Hi -- I hope someone can help with this recent problem that has cropped up. Videos that are supposed to be autostart, such as news stories embedded on pages of news sites or video feeding into a side panel on a college sports site I frequent are just continually in buffer mode with the little spin icon in the middle of the screen. This also happens with some, but not all, YouTube videos.

This is a recent development and I didn't do anything to change my setup. I did try updating to make sure I have the most recent version of Firefox, so that's been accounted for. If I close out Firefox and come back to it after a couple of minutes, the problem is cleared, but it only lasts a little while before it begins once again.

Any suggestions? Thanks!

I'm not very computer savvy but I followed a website a few months ago to edit Firefox so it'd default to dark mode. I think I went in and edited source code? I can't find the instructions anymore but I'd like to revert back to the original setting. How do I do that? I tried to refresh Firefox but it's still coming back with some websites in dark mode and some not. Please advise!

I haven't been using Firefox for awhile since i lost my old laptop and phone (to be exact its 4 years or so) and now im back on using it, but i was unable to log in to this exact account at first since this what was prompted when i try to use my password (image one), i did try ask for a password recovery which the same error appeared but for some weird reason after trying it on the mobile version it let me use the google login and im able to get access to it. but it still wont let me change password, add passkey or add 2FA. is this some weird issue going on or am i missing an email or something??

I was using PC and a window popped up saying "allow Firefox to make changes" and I clicked allow! Shortly thereafter my PC froze and I had to power it down. Now Firefox looks completely different and all my bookmarks and links to everything is gone. Also all my saved email logins and information!

Please help me reverse this change, I hate it!! Betty Turner

How can I see what cookies have been installed? In "Privacy & Security" | "Cookies and Site Data" I can see the web sites that downloaded cookies and how many, but not what they are.

If I add sites to 'Exceptions - HTTPS-Only Mode' list, I expect that sites are preserved after browser close and restart. But after I close and restart Firefox, the list become empty.

I don't know why this happens. I even deleted every profiles and created new profile. The problem still exists.

Is there any way to manually add HTTPS-Only exception list by editing files in profile directory like 'prefs.js' as a workaround? If Firefox can't save the data, I will manually edit that file and mark it as read-only.

I recently changed to Firefox from chrome and the focus on security and privacy was a much needed upgrade. However, every time I close my windows I'm logged out of all my accounts. I checked all the settings that would have that effect even escalating it to a clean install and unfortunately nothing works. After checking the support forums this setting seemed to be the one that fixed things, attached is a screenshot showing that its unchecked and that there is cookie data stored, so I'm really at a loss.

Today, out of the blue, my email screen adjusted itself to be very, very tiny. I almost need a magnifier to read it! I cannot find how to put it back to normal!

Please help!

Hello team I am not an developer but sometimes i use inspector to see if the 'get' requests are working properly. But for some time when i try to close the inspector after i am done ,it just stop and doesn't close. this makes to close the tab while doing something important. Please check this problem and give me some solution.

For some time, I’ve been using characters like em spaces (U+2003, or ‘ ’), thin spaces (U+2009, or ' ’), and hair spaces (U+200A, or ‘ ’) on my webpages, and up until a few revisions ago, Firefox was displaying them appropriately. Rather abruptly, they were replaced with boxes.

This doesn’t appear to be a font problem; it happens with every font, including several that I’ve verified have the character in question. (In the image below, it’s in Times Roman, but I’ve tried Noto Sans, Arno Pro, and half a dozen others.)

Does anyone know why this is happening, and does anyone know a workaround?

I found an answer to this question, but I need it in English; how to do this if you're not a programmer. The new feature is beyond annoying, so if someone wants to work on making it optional, that would be a super improvement, but I'll be happy if I can just turn it off! Thank you

I am developing an extension that will fix YouTube spacebar issue (after recent YouTube update after Alt Tabbing from other window, spacebar is not working to Pause/Play videos).

The problem is that my extension is not working anywhere except on https://www.mozilla.org.

I've already added "*://*.youtube.com/*" to "host_permissions" in my manifest.json file and it's displayed as "Can always read and change data on this site" on YouTube, but it does nothing. On https://www.mozilla.org my extension is activating properly (writes test message in console).

I added my extension on "about:debugging". Can it be related with that? Appreciate any help!

When I want to do a google search, it will only do an amazon search. So if I am asking a tax question, it brings up amazon products to buy. I can't search anything. Very frustrated.

I'm having an issue that seems to Lock up YouTube on Firefox.

I'm trying to get back into using Firefox but I'm having a persistent issue in both FF Mainline and even in FF Beta 119.

If i play a Video on YT then switch tab to do something else then go back to YT it lock up the video window. I do not have this happen on Chrome or Edge.

I have tried refreshing the browser and still have this issue.
