I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

Yesterday I switched on my PC, opened Firefox and the home page was black. See the attached screenshot. This is not caused by some accidental switching on of the dark mode. Dark mode is clearly off. Neither can I adjust settings to make the Google home page revert to its customary light grey shade.

This isn't a big deal, I know. And it has happened before and in a short period gone away by itself. Maybe it is to do with a glitch in the latest Firefox version. But it has an unpleasant appearance and discourages surfing.

My Chrome Google home page doesn't have this issue.

Can anyone advise on how to fix this unwanted black screen problem ?

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

Every time I access the web I get a report from Norton saying "Threat secured". It attaches every single website that I open. See attachment for some exmaples (only variabole part of message shown apart from first one).This is occuring 50+ times a day but does not occur using Edge, so it appears to be related to Firefox. PLEASE help. Norton have not helped with this. Thank you- Colin O'Brien

Hello,

I am trying to download a few JPG images from Meetup.com. Here is an example URL:

https://secure.meetupstatic.com/photos/event/3/5/0/a/highres_528673578.jpeg

This is CLEARLY a JPG image from the URL. However, when I right click on the image to Save As the only choice given is AVIF! I cannot open or use AVIF files. As you know the conversion process is LOSSY so trying to convert BACK to a JPG format is not recommended.

It is fine if Firefox and other browsers want to use AVIF format internally but you should, at least, give users the OPTION of downloading the native format.

So how do I fix/configure Firefox to provide the native JPG file download?

Thanks, Steve

This what you said: "Today we’re introducing a free built-in VPN in Firefox, a new IP-protection feature designed to keep you even more private while you browse. We’re starting by offering an industry-leading 50 gigabytes of free VPN-browsing each month." But all I see are the paid options. I want to try before I (might) buy. After all, you constantly preach that we have to be careful & trying to be careful.

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

I can no longer enter a password on the login page at https://secure.bankofamerica.com/login/sign-in/signOnV2Screen.go. I was able to change my password but it didn't help. A BofA agent could not identify the problem and walked me through the login using Chromium.

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.

For about the past week I've been having trouble with Gmail and Google Search in my Firefox browser. Typically, I open a Firefox window with multiple tabs and leave the window open all day. I always have Gmail and Google Calendar open in tabs. What happens is that the Gmail tab will at some point give me a message that it cannot connect and has timed out and is trying to reload, but it never reloads, it just stalls. Then I try to open a Google search bookmark to search and the tab remains blank. This happens multiple times throughout the day. Meanwhile I can open Gmail or any Google page in Chrome, which I don't like using.

Sometimes I can close out the Gmail tab that won't load and try to open Gmail in a new tab, but that stalls out too. The only way I can open Gmail again is to close out the Firefox window completely and then relaunch it, then it can open Gmail or Google... until it breaks again.

This never used to happen. I'm using the latest versions of Windows 10 and Firefox on my desktop PC. Nothing else has changed.

Please help me fix this, it's very annoying.

Firefox releases email addresses and our data to third parties!

I installed the Arc browser and Arc offered to load my bookmarks from mozilla. Out of curiosity, I let it, and it loaded my bookmarks and folders smoothly. Arc didn't navigate Firefox to the login page, so Firefox released my information without asking me.

What probably happened in the background was that the Arc browser told Firefox which email address it was requesting data from, and Firefox handed over the data to it "on notice". Firefox was not even convinced that the real owner of the email address asked the Arc browser to synchronize the folders.

Is it the famous Firefox reliability?

I am going to switch OS soon, with open core patcher.. I alreasdy lost 2 years of bookmarks 5 months ago, I can't have it happen again.. What is the easiest way to save my book marks for new OS / COMP?

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

I keep experiencing this problem with different websites: Safari works, Firefox doesn't.

Sample: I turned out the enhanced tracking protection, Privacy is set to Standard for

https://search.ccb.state.or.us/search/default.aspx

I entered valid license numbers (230880, 239798). Firefox displays NOTHING, no error message. Safari displays the relevant info.

Why is this and what should I do if I want to continue using Firefox? Thanks.

The mute tabs icon is just a waste of space as soon as you get a few tabs loaded and the tabs shrink. I have multiple tabs showing at the moment where I have clicked on the icon and unmuted them when just trying to select them. It does not help that the icons have been placed in almost the exact centre of the tab, at least with the 19 I have showing in a mix of muted/unmuted. Only 7 of these tabs are still muted, although I did deliberately unmute one to check the action.

I would prefer it if these icons are not showing as they are a waste of space and my time. If you hit the icon the tab is not brought to the front as intended so you have to click on them again. I just want the tabs to work like real tabs.

Is there any way to remove the feature altogether? I have after a lot of frustration just reduced the sound for Firefox in the Windows Volume Mixer as I did before tab muting was thought of. I almost never use sound in Firefox anyway.

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?

I downloaded Firefox not too long ago to combat the fact the Microsoft Edge wasn't working correctly, but ever since I downloaded Firefox it's been making my computer run really slow on the browser. Things are often slow like scrolling up on and down pages websites like Pinterest, and the text when typing on Google docs takes a moment to show up after I've typed it and not instantly, for example.

I checked my computer's task manager because I recently cleaned the laptop, thinking that something else was causing it to be slow, but it isn't. I don't have many processes open on the computer mainly mandatory things and my browser, since I use my laptop mainly for school work, music, or writing. Firefox opens multiple processes, the highest being 21 at one time, and takes up most of the memory on the laptop. Is this normal? Because it takes 1,094.0 MB and keeps my laptop's memory at 90-91%. If it isn't normal, how can I reduce this as well as the lag on my laptop when Firefox is open?

I attached a photo as well.
