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.

Hi.

How come there is no option to turn off "Firefox Translation"? I speak three languages and every time I visit foreign web site, Firefox suggest translation to me. It's annoying.

I am a bit confused about how to keep updating FF on my Windows 7 PC, given that after March my current version (115.17.0esr) may not work as intended. Until now I've always updated manually by downloading a small 343KB installer file that updated FF without changing any of my settings, logins and bookmarks. Hoping to simplify updating, today I set updates to "Automatically install updates (recommended)" with sub-option "When Firefox is not running". But just now a FF notification informed me it was unable to update automatically and provided a link to https://www.mozilla.org/en-GB/firefox/enterprise/?reason=manual-update. From the dropdown there I chose "Windows 64-bit" > "Firefox Extended Support Release (ESR)". The download is a 64MB file.

Since this seems to be a new installation and not a simple update, can I be sure it won't overwrite my current version and leave me without settings, logins and bookmarks?

Firefox Android on an older Sony Xperia Android Tab (2016) still receiving Firefox updates, would you believe it, cannot access about:config page -- and yes it's about:config I'm attempting to access. Firefox adress bar icon displays site warning and freezes the page load whatever setting i try in Firefox settings.

No antimalware or such nonsense used on the device, just as fake in protecting my privacy as (foreign) gov.-sponsored whitelabel antimalware and privacy search engines -- remembering the recent Bing API-blackout that displayed a Bing search engine error message in all of the so called's etc etc

I'm not logged in on the device, as in not syncing an access all home living room device in any way. I don't need a breadcrum trail of other users leading to my accounts.

So what am I after? I don't want a stored cache of recently visited pages that apparently hog the limited memory and I want to limit the amount of 'recently visited pages'-cache stored in Firefox on Android. I want Firefox to be *pristine (beyond the moniker settings available as 'clear all' at Firefox close) each time a user picks up the tab. So, there's one or two settings under about:config limiting the recently visited pages cache to the latest visited only after closing Firefox -- lowest setting available (?) is 0, but hey, that's life.

I have run across threads with similar questions in both mozilla support and reddit, but as they are old and archived I cannot add additional info or request clarification, so here is (yet another) new one- I understand you can go into manage data in settings to delete what you want, however in mine it only shows a handful of most recent (opened today or currently open) since my settings clears history and deletes cookies upon exiting ff.

Cookies and Site Data section shows only 40.7mb of data is stored and in Manage Data only shows 8 sites... Clear Data area, with only these two boxes selected (attached) and 'everything' (time) still only around 50mb. My storage/default folder has 1005 folders and the data is over 1.5gb; I would like to manually delete all of this and as others have tried to ask, am wondering if this is ok to manually select them and delete in windows, or using windows %appdata%(?) and if so, will the sync feature (if I just clicked 'sync now') still retain all my bookmarks when I relaunch ff? Not concerned about any browsing/form history or passwords, only bookmarks.

The inbox font in the Thunderbird email client on my Mac is super tiny, and it's very hard to read. I can't figure out how to make it larger. Is there a way to do this? I really like Thunderbird so far, but if I can't read it, I can't use it.

Thanks! Mark

I initially used the K-9 email client and switched to Thunderbird sometime last year. For almost a year now, I haven't received any notifications from Thunderbird when new emails arrive, which I believe worked initially.

Then new emails weren't displayed at all; I had to manually refresh my inboxes and folders. A recent update seems to have fixed at least this issue, as new emails are now available when I open my inboxes. However, I still don't receive any notifications.

I have also checked the notifications settings and the permissions, it is always mentioned that the "Alarms and reminders" permission is required, but I don't have this permission. Reinstall the app and reconfigure from the Windows Thunderbird didn't helped as well.

Any help is very welcome; I don't want to reset the device hoping it will work, only to find out that it didn't help.

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. 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

I just updated Firefox to version 135.0 on my mobile and now I get this really annoying thing:

Everytime I open a tab to go on the YouTube website, it asks me if I want to leave Firefox and use the YouTube app. Every single time. And it even launched it once without asking me.

I don't want to use the YouTube app, how can I make this stop?

Have a good day!

Taskbar icon does not indicate when new mail has arrived. Does not show a count of new/unread messages. 128.3.2 Windows 11

In settings "incoming mail" icon options I have chosen "show count of new emails" and "show a tray icon for unread messages is checked".

I am unable to tell at a glance if new email has arrived. I see from researching the KB I'm not the only to have this issue, but none of the settings seem to 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.

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.

When I select "Edit as New Message" in Thunderbird (v52.9.1) on a Mac, the message editor comes up in html mode even if I have set everything to plain text.

I have read all the articles on this and done all the things people have recommended including messing with Advanced options, account settings, etc. However, none of these solutions work.

Attached is a screenshot showing the problem. The first screenshot shows my inbox. The second shot shows that "Edit as new message" comes up in html mode.

Please advise.

I recently downloaded Firefox on my Android device. It's been fine. However today, there was an issue. I have the settings set on my phone so bookmarks appear on the homepage. However, today, for some reason, the bookmark on the homepage was glitched. I'm not sure why, but I figured I just had to reset it. So I go rid of the bookmark on the homepage, and redid the bookmark. It was working again, but now, the bookmark isn't appearing on the homepage anymore. It's just a blank homepage, even though my settings are still the same. I've turned the settings on and off, reset fire fox, cleared cache, and the bookmark still isn't showing up. Pleas help me.

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!

How do I get the + sign back on my tabs? After latest update I can only close tabs instead of opening new tab, and I am talking about after opening several tabs. When I have seven tab open, I have to do ctrl+t to open new tab instead of just clicking on the + sign that use to be at end of tabs. Yes, I do use custom settings. This happened before but I was able to fix by going to tabs under about:config, but it seems the setting is no longer there.

In the article https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended

https://packages.mozilla.org/apt leads to 404, not a Debian software repository / archive.

Step 4 (is broken)

Next, add the Mozilla APT repository to your sources list:

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

New day, new glitch. Since the inception of weather showing on the Firefox landing page, it has accurately shown my location. Today, it is not only not my city, it is in another state. It also does not respond to my making a correction with my zip code. Can we expect a correction any time soon?
