Hi! I have latest version of Firefox installed on my PC. But sometimes I am programming for web. So I would like to have Firefox Developer Edition as well. But I don't want them both at the same time - one for my usual web surfing and another one for web programming using leading (or even bleeding) edge features.

How do I install and use them separately? I tried running Firefox Dev Edition installer, but it does not ask questions like where to install and which Firefox profile to use.

Every time I restart Firefox, places.sqlite which is currently 105MBs changes to only 5MBs and a new file named places.sqlite.corrupt appears. If I open Firefox, all my history is gone. If I rename the .corrupt file to places.sqlite my history comes back. I want to know why it gets corrupted? It happens when Firefox closes and it doesn't matter if there's a power cut, closing with X , or Exit, Firefox restarts and I have to rename the places.sqlite.corrupt file again. This has been happening for almost two years now. My computer stays on 24/7 and I may restart it once every 2-3 months, but sometimes you have to restart it many times a day because of issues and it's a pain in the behind to rename the places.sqlite.corrupt every single time. Any ideas?! Could an add-on be affecting it? I don't have a lot of them. Just basic AdBlocks.

Thank you.

Hi there. My scroll wheel on my mouse stopped working. Only way to scroll is to press Ctrl+Shift and then use scroll wheel, which makes it work fine. But i would prefer to not have to press down Ctrl+Shift to scroll. This problem is only happening on Firefox and no other browser or program on my computer. Do you know any solutions?

I have researched and found out many people had this error but no one got a solution, same for me. examples: https://www.reddit.com/r/firefox/comments/sry42x/this_page_is_stored_on_your_computer_icon_showed/ https://bugzilla.mozilla.org/show_bug.cgi?id=1677909 Please help.

I have just updated Firefox, and I am not able to scroll at all. My mouse wheel does not work and the mousepad scrolling does not either, but I am still able to scroll by pressing down the scroll wheel (image below). I am able to scroll on all other applications and I was able to scroll on the 'Which topic best describes your question?' mini-menu, I'm just not sure why I can't do it on here. Thanks!

I currently use Chrome on Android & Chromebook as my main browser, but I would like to switch to using Firefox now across all my devices (linux, android, chromebook). To do this, I need to import my passwords from Chrome to Firefox, and have them sync between the Firefoxes on all of my devices, but it's not working. I have tried the following:

Method 1: I installed Chrome on my new Linux machine. Checked and made sure it had synced my passwords by logging into a website using Chrome. Then, on Firefox, I pressed alt to enable the toolbar, then File->Import from another browser. The pop-up says "No programs that contain bookmarks, history, or password data could be found."

Method 2: Chrome seems to have a feature to export the passwords to csv. So I exported the passwords from Chrome to a csv on Linux. To be thorough (because I am having trouble getting this to work), I used accounts.firefox.com to sign out the Firefox on my android phone and chromebook, then (on the phone) I deleted my browsing data, uninstalled firefox, and rebooted the phone. Back on Linux, I did about:config, then set signon.management.page.fileImport.enabled to true, then did about:logins then menu->"import from a file", selected the csv that I just exported from Chrome, and clicked Import. Import Complete, 332 logins added, 1 not added because it was missing a password. Logins successfully imported, hooray! For testing purposes, I create a unique new password entry, http://foo.com username "a" password "b". Then I go to about:preferences, make sure that syncing is on and I'm currently syncing logins and passwords, and press "sync now". Log in to my phone, install Firefox from the play store, start it up, sign in using my email and password (it says "syncing"), go to logins and passwords, click "saved logins". The only one listed is for foo.com, the fake one I created to test the syncing, but I expected to see all 333 there.

How do I get this to work?

the latest firefox update has disabled scrolling/ i have tried changing the settings in firefox and no changes make any difference. scrolling works on other apps perfectly fine.

Two updates ago, I had an issue where if I used any Google web products, I had weird network problems that just didn't go away (4000ms ping spikes every 5 packets). I noticed it was only when I was using Firefox, so i tried disabling add-ons and extensions, it still happened. I opened it in safe mode, it still happened. I tried using Chrome and Edge, both did not cause issues.

I reset my Firefox completely (There was some custom CSS to put tabs on bottom, where they belong) and it was perfectly fine! No issues! Everything was great for a few days!

Then you guys updated things again... and it was back... so I reset my Firefox again, and even straight out of the box, its still causing the issue, but now only when using google products, with or without add-ons, there is no custom CSS anymore either.

I do not know why its an issue, but it is, and it is ONLY with Firefox, and I really do not want to switch to Chrome or Edge... It also persists after Google is closed, until I restart Firefox.

I am unsure of specifically why this is happening now, but it is a MAJOR problem for me

I normally have my bookmarks showing to the left of the main window. I have many, in various header categories like medical, games, finance, etc. Recently I was doing some and wanted to close the bookmarks to give me more room for the main page. I THINK I did it very easily with a right click and close folder or some such thing. Worked great. I got to have more of my display to show on the page.

I am now incredibly frustrated that I can't get them back. I have done research and tried to follow the directions but can't get it to work. I have found Bookmark Tools and Options and I have "always show" checked. But I can't get my bookmarks back to the left of the main page where I can easily go to where I want to go.

I need help! Please. Very frustrating.

Summary Reset a site or domain to be no longer associated with a Container

I accidentally assigned my search-engine domain to a container. As a result every single search I perform from the URL bar asks if I'd like to open it in the assigned container instead. I'll select 'Remember my decision, open in current tab' (the current tab being the base no-container Firefox user). Unfortunately this does nothing.

I've searched through the settings and options and I've found no option to get an overview of the domain configurations or to reset a certain site. I've read suggestions online to delete the container, but this isn't an acceptable approach to the problem.

bold text I need to save all of my bookmarks and history so I can add them back in after wiping and reinstalling Windows 10 and then reinstalling Firefox on my computer. How do I do that?

I've attached an image of what's happening to me. Since last update, the toolbar is 50% allocated to blank space which cannot be used.

For example, I cannot drag to resize the search box across to the left side of the toolbar (which is where I like it), nor can any item be dragged or placed there.

I'm pondering (if I know how) installing an older version and preventing updates etc.

Is there another solution? Is anyone else seeing this?

Any tips would be hugely appreciated.

Hi, I have noticed that when using the latest release of Mozilla Firefox on Windows 10 and Ubuntu 22.04 LTS, when I go to ABCnews.go.com and click into a story, there is an autostarting video. But instead of either waiting until I click on it or autostarting normally, it flashes wildly. I have disabled all extensions and the problem persists. Has anyone else encountered this? And more importantly, does anyone have a fix for this issue?

Maybe this is obvious and I just don't know the proper terms to find a solution, but I've recently lost the little loading icon that spins in the left hand corner of a tab when you load a site (see gif). No idea what happened to it, but I've tried refreshing and reinstalling to no avail. Yesterday I reinstalled Windows 10 on my machine (not because of this) and it worked correctly until I booted up this morning and it's switched back to that weird icon. Any ideas how I might fix it? Could something like a windows update have messed it up? I miss that little spinney icon more than I would have expected.

whenever I long press on an image I'd like to save, nearby text gets higghlited instead and I'm not offered the usual pop-up window - in Google search for example, text saying 'realted images' gets higghlited

When I do the keybind (Control + P) or press the print icon in google apps (google docs, drawings, etc) it automatically downloads a pdf instead of opening the print menu. Chosen solution

Printing on any other site pops up with the printing options. Only on google apps does this happen, including gmail.

This problem is non-existent on Google Chrome and Edge. It does persist on Brave although. Haven't tested any other browsers.

I'm not sure when this changed, but I can no longer shrink my search bar to make room for more extension shortcuts. There's no double-arrow, no option I can find in customizing (I've tried the unsupported compact thing). I've gotten myself so worked up over this, I'm sure I'm overlooking something obvious.

Thanks for your help.
