I had about 20 tabs in my "Inactive tabs" on Firefox mobile. Today I wanted to open one of them, but all gone. I can't even found them in "recently closed tabs". This is very upsetting because some of them was very important for me.

Hello why my firefox installation 1440b6 64 bit on windows 10 do not autocomplete the third field in a form login ..

namely , username and identification password are correctly filled , but the third field (that in my case are named "company ID") would not, it remain empty, and i need to manually fill in each time. Actually this happen only on a one site , but may be because only this site that i use have a three field to fill in the login page...all the others need only password and username

thankyou kind regards klx140

Hi, Being that OLED and AMOLED screens have become more frequent in recent years (and seem to be coming to stay) I am perplexed by the seeming impossibility of finding a way to make Firefox more friendly towards these devices.

I would like to use Firefox with a true black theme on its UI that would waste less battery and go easier on my screen's long-time durability. However, not only do I find that there is no option to do this in-built on the app, there isn't even support for external add-ons or thèmes that could get the job done!

There really shouldn't be any reason why, even if the Mozilla team are unwilling to code the option into the default settings, it couldn't be done through a user-made theme.

Instead, the solutions I've come across seem to span from third-party apps that require rooting the device to modifications made directly by decompiling the APK!

I know this was more of a complaint than a request, but heavy battery usage is a *valid* reason not to use something like a browser, which is likely to accrue several hours of use each charge cycle.

This *is* something Mozilla should care about.

TLDR;

Please point me to a way of making the Firefox UI AMOLED-black that does not require me to mess with the internals of an APK or void my phone's guarantee.

Sorry for the essay.

In the dialog box of this website https://www.doubao.com/chat/, you cannot paste images from the clipboard, but Edge can do it.

Hi,

I have logged out from some device (laptop) today. I had approx 150 tabs over there I would really like to recover. Is there any chance to get them back?

Kind regards Grzegorz

The latest update for the beta version 153.0b1 of 6/16/26 has made my theme stop working although it still says enabled. The theme is: ANIMATED Sakura by candelora 🌸 Theme Designed by candelora © 🌸 Animated Apng Theme I'm using Windows 11 on a Lenovo IdeaPad Flex with Firefox as my default browser. I'm an old lady, not tech-enabled in any way. Please help and thanks.

Getting a weird issue. When I open Firefox Beta, if it is not already running it loses focus on Firefox and pops open the Google Play Store over the top of Firefox on its Firefox Beta page. It's doing this consistently and repeatably. I'm on a Samsung Galaxy A52 5G on the latest update of Android 14.

Hi, Every time I search using Firefox (especially through the address bar or default search), SafeSearch is automatically enabled — even though I never turned it on and don’t want it. I’ve tried checking Firefox settings, search engine settings, and even my browser profile, but nothing seems to work.

I’m not sure if this is a browser setting, an issue with my account, or something being forced externally (like by Google or Bing).

Can someone tell me:

Why SafeSearch is always on?

How can I turn it off permanently?

Is this tied to Firefox itself or to the search engine provider?

Using latest Firefox version on Android 15.

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

When I go to another app, and back, tabs have to reload, often loosing what was done in the page. I have set Firefox as "No restrictions" on my Xiaomi 15 Ultra (HyperOS 3, Android 16), but Firefox still seems to unload memory very frequently.

Sometimes I want to enter arbitrary IPA strings into websites from my phone. I've tried finding a privacy-respecting way to conveniently do this and the best way I've found so far is to use the app Unicode Keyboard by Tim Wunderlich, available on the Google Play Store, and enter the code point for the IPA letters or diacritics I want. This works in every other app, but in Firefox, there are two characters I can't enter this way - the combining grave diacritic U+0300 and the combining acute diacritic U+0301. Even other combining diacritica work. I like researching and talking about linguistics and conlanging online, and sometimes this involves using those diacritics to mark tones. This is such an odd specific incapability for Firefox to have but it has persisted, since at least as far back as 2024. I've just had to enter those diacritics in another app and copy&paste them in. I can enter the diacritics directly as keyboard input in Firefox on Windows and GNU/Linux.

hello good day i know this is asked many times but i've tried a lot of solutions that i can find online but none works so here i am... https://share.firefox.dev/4uKI7Xf im running firefox in a windows 10 virtual machine, 3d accelerated, some websites (even google sheets) that make my firefox use a lot of cpu check/uncheck "Use hardware acceleration when available", uninstall, troubleshoot mode... is no different any help is appreciated, thanks

Is there any way the recent changes to the browser on IOS can be reverted in a future update or at least have the option to change the layout ? The recent changes make absolutely sense and are frankly aggravating as a longtime user, It honestly feels like a joke to suddenly have the tab names below the tabs and the tab menu at the bottom of the screen. Duckduckgo is looking more tempting with every recent update :/

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

I cannot find "Sync and save data" button in my mobile browser, making it impossible to sync the devices. The instructions provided by the settings lead me into the dead end.

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?
