Firefox Community Forum

I just acquired a new Windows 11 computer, and I have installed Firefox. My old computer quit suddenly. I am trying to find the Firefox file location. There is no Mozilla or Firefox folder in "Program Files", "Program Files (x86), "Downloads", "Users/Appdata/Roaming", or any other location that I have thought of. I want to bring in my bookmarks from my old computer and I only have access to the files in the "Users" folder.

Where might these files be?

If I select "Privacy & Security > History > Clear history when Firefox closes > Settings > Data > Site settings" what SQLite files affected when Firefox closes?

I suspect in the profile folder directly, there's a file called "storage.sqlite", but there seems to be more things affected because the whitelist for my cookies is also wiped-out.

In my experience (115.23.0.esr), when I request to remove site data when Firefox closes, it wipes out my cookie white list, so I want to manage that myself.

I do not and will not use the sidebar/vertical tabs features.

Unfortunately, it seems that firefox has decided to reactivate these features with an update? This is unacceptable. I do not want my settings to be altered with a software update. If firefox wants to tell me about a new feature, feel free to make a dialogue bubble pop up (once) asking if I'd like to explore said new features. Otherwise, please refrain from altering my preferred configuration without permission or notification. Doing so is completely asinine at best and shows open contempt for your customer base at worst.

I do not wish to give mozilla/firefox another opportunity to make my experience worse, thusly I ask: Is there anyway to entirely remove/disable the sidebar/vertical tabs feature from the browser so that it cannot be reactivated without the specific actions of the user?

i can change font size in general via firefox settings, BUT!

whenever i want to download a file from any given website,
the download window that appears, in which i can navigate to a folder on my computer and choose a name for the file,

has such super small font!!! and to make it worse, the text largely in a soft gray rather than a nice strong black! SO hard to read. i would love an easy way to make this font always bigger for all these situations. if anyone can provide the solution im super grateful!

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

Just installed Firefox for macos Monterey.

On the "Home" tab in preferences, it lets me enter "https://www.bing.com" for the Firefox Homepage. Then for New Tab it lets me select "Firefox Homepage".

However when I open a new tab, I still get Firefox page with a Google search box.

What am I don't wrong? Thx

A sidebar has appeared out of nowhere. I removed all extension on that sidebar and it still doesn't go away. I already have a bookmark bar and extensions at the top bar. I don't want another sidebar at every firefox window. How do I remove the sidebar, please.

The bookmarks icons and fonts are too small for my older eyes on my new Ubuntu computer. They are bigger on my older Ubuntu computer. I have tried to find out how to enlarge them without sussex.

I am aware of the Zoom feature for a webpage itself, I am not asking about that. I simply want to have my bookmark toolbar FONTS and ICONS larger.

This has been frustrating. Perhaps including an EASY way to do this for future updates, or an app suggestion that would solve the problem. Thanks for your consideration and (hopefully) help.

I'm visually impaired and had originally used a CSS code to fix this problem, but that was a couple of years ago. I just upgraded to 131.0.3 (64 bit) and evidently, that wiped out all my CSS changes. I tried to use the about:config code to change it, but it no longer works. I managed to increase the icon size a little by changing the density to normal, then back to compact. Even on normal, it was all too small.

I don't want to use another profile, because every time I do, I lose so much that it takes me hours to reinstall it all.

Is there an easier way to do this? I've tried a couple of things suggested online, but they were old settings suggestions, and they no longer work either.

ALSO, I now have to use F11 full screen to be able to perform anything on the toolbars. Before this update, I could just move my cursor up to bring the toolbars down, and use the back arrow or refresh easily. Now, the toolbars immediately go back up and I have to use F11 to do anything. How do I fix this?

TIA for any help you can give me.

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

Hello Firefox friends o/

Anyone knows how do I make https://yandex.com my default search engine? (in the top bar of the browser). I have attached a screenshot of my settings page. Please have a look at the suspicious lack of an "Add" button 🤔. Despite my efforts, the drop-down menu will not show the available options in the screenshot, you will have to take my word for it, the only available options in that menu are: Google, Bing, DuckDuckGo, eBay and Wikipedia (en).

P.S. The settings page in Firefox must change really often, as I seen so many people suggesting many outdated methods online.

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?

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

The other day I accidentally pressed a keystroke that changed a Firefox setting, and now it thinks I'm on a mobile device/displays sites in mobile view where possible by default. This has persisted despite restarts of the browser and the computer and has been happening since Sunday (Australian time). I've tried opening the Responsive Design dev tool and I've sent screenshots to a techsavvy friend (I'm totally blind and use a screen-reader, so couldn't tell this was happening until I tried to use a site that had a radically different layout in mobile view), and aside from not seeing an exit button or a switch to change device mode, he couldn't tell what was going on.

I'm stuck and need help! I would like to unmobile my Firefox!

I had a background image for the new tab page that has suddenly stopped working, it just displays a white screen. I clicked the 'reset to default' button next to 'Wallpapers' on the new tab page to try to fix the problem but nothing happens. No wallpapers show up under that section either where it used to be when it was working. I've restarted Firefox and the same thing happens. I have not enabled any third party CSS wallpaper.

Apart from that, everything else is working as it should. I'm sort of a computer-idiot so if anyone could please use layman's terms it would be very much appreciated!
