Ever since yesterday, scroll click (I use it to scroll through websites) has stopped working in Firefox. Works in in programs, other browsers, etc., just not Firefox.

Whats weird is it still registers a click when I use it, so I can lick on links with it if I want, but the function of scrolling, either by clicking once and using my mouse to go up and down, or by clicking an holding, no longer works.

I've tried disabling add-ons, incognito mode, nothing seems to work.

When refreshing and clearing cache using CTRL+Shift+R, browser should reload all assets. However when refreshing site with @import(ed) style sheet, it does not update.

The workaround is to open the style sheet in a new tab (e.g. https://my.web.com/assets/custom.css) and run refresh + clear cache there CTRL+Shift+R, which loads the updated style sheet.

Then, upon refreshing the original site (https://my.web.com), the CSS has been updated.

Is this a bug or expected behaviour?

When opening an email with an attachment (either a pdf or picture) in Yahoo mail, the Yahoo mail tab closes and I have to then reopen it from History, Recently Closed Windows. It's been dong this for some time now. Does anyone know how to fix this?

I told Firefox to never remember a website login user/pass but now want to revert this. I have looked for this option but can only find the remembered user/pass. There is an option at the bottom of the chrome password list, but not in firefox.

Can someone please point me to the area that i can remove this "never remember logins for this site"

Thanks in advance

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.

I want to disable ad blocker. I actually want to see the ads. Since I did the latest update, ad blocker is turned on, and there appears to be no way to turn it off. How do I disable it?

Since Firefox for Windows upgraded to 105 the Wordle web site fails to work - it displays the grid at the bottom of the window with no scroll possibility & it displays that even when a correctly working browser displays my statistics.

The website works correctly on other browser (Chrome & Edge), on Firefox for Android and on Firefox for Windows 104 (luckily I had a machine which hadn't been on for a few weeks and therefore was no up to date).

The attached images show the website as it should be (on Chrome) and as it appears on Firefox 105

OK, I have read (ad nauseum) every Fix to not getting sound while using Firefox. I disabled Hardware accelerated Graphics, Cleared cache, cleared history, disabled all addons, updated Firefox, uninstalled and reinstalled Firefox, etc. Nothing has brought the sound back.

I have sound on my computer and on games and in Google Chrome and Microsoft Edge but not Firefox. Anyone know something that I may be missing? PLEASE HELP! I wish Mozilla had Tech Support! :(

I've read the forums, i've tried adjustments for days on Win 11 and firefox. Zoomed in zoomed out, adjust font sizes Either it's way too tiny to read or the page is fine but text over laps i've tried the zoom in on text only as well Basically tried everything. enclosing a youtube page for reference

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.

Recently, I've started noticing these quick action tiles in the URL drop-down menu (I've attached a screenshot). There's a help icon to their right, but it just goes to https://support.mozilla.org/en-US/kb/quick-actions-firefox-search-bar?as=u&utm_source=inproduct which is a 404. I found this bugzilla bug, but I'm not 100% sure on how the versioning works (even after consulting Wikipedia). The bugzilla entry mentions it's fixed on 105.0a1. I'm using 105.0b6 of the Developer Edition.

HELLO very small cursor on Firefox windows (on all other windows the cursor size is normal) via snap after upgrading to ubuntu 22.04.1 LTS. how can i change it? Thank you

Hi Firefox community,

Do we have any settings in firefox where we can enable/disable dark mode in firefox browser instead of installing a plugin or addon? I am looking something that is offered within the browser instead of a plugin.

Thank you all.

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?

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.

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.

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.
