Firefox for Android Community Forum

Since version 134 of Firefox Android has been out, it crashes EVERY TIME when I try ot use the "back" gesture on my Xiaomi 14(i.e. swiping from right or left side of the screen) I tried Firefox 134, Iceraven 2.27 (also based on the same Gecko) - they act the same. In the same time I also have Waterfox, based in the previous version of Firefox 133, and it responds properly. I guess it is related to the latest version only. Here's the crash log:

When playing a video, the audio crackles severely, this only happens on nightly, not on regular firefox or other browsers. This issue is not exclusive to youtube and seems to get worse the more the audio is speed up

I gave my laptop away. Absolutely cannot get my Firefox info off. She can't get logged on to anything because it thinks she should be me. Grrr.

How to get a clean install without Mozilla finding hidden info and putting it back in?

Now it's completely impossible to open PDFs outside Firefox, as I could do until the last couple of beta versions.

This trend is going on since a few years ago, from bad to worst. The whole design of the PDFs download process is bad. PDFs should be treated by FF as any other file: download and open with the system default PDF viewer. Imposing Firefox's internal PDF viewer as mandatory for downloaded PDFs is nonsense.

Firefox for Windows supports server certificate error exceptions (Settings->Privacy&Security->Certificates->View Certificates...->Servers). Is there an analogous feature in Firefox for Android? If yes, how can I see/modify my exception list?

Current browser version: Firefox (Android)134.0 (Build #2016064983), hg-b8005f63d9eb+ GV: 134.0-20241230151726 AS: 134.0 ___

Hello everyone,

Previously, it was possible to configure Firefox so it would stay in the background while opening tabs from links activated in other apps. Thus, said apps would stay in the foreground until Firefox is called to the front.

The desired result was achieved by editing the setting `browser.tabs.loadDivertedInBackground` in "about:config", which is no longer available.

If such a configuration is yet possible, how is it achieved?

Thank you.

I keep getting logged out of the accounts I sign into on websites in Firefox Mobile. I haven't activated any settings to clear cookies or other privacy options, but I still get logged out of many websites. I have to log in again every time I want to use various websites or services. If anyone has any information, please reply. Note: I have only installed the uBlock Origin add-on.

I have just updated to Firefox v134 stable release on Android and now when I log into github.com, the webpage is glitching and not being rendered properly. The avatars on github look torn and they are blinking when I scroll up and down. This is occurring with current Firefox stable, beta, and nightly releases on Android.

My device is a Samsung T813 tablet running Android Nougat (Android 7.1).

I should also mention that Firefox v134 on Android is also showing UI glitches when viewing the settings in certain extensions, like FoxyProxy. Although, I have also done a clean install of Firefox v134 with no extensions installed and the webpages like github and still showing the rendering problems mentioned above.
