YouTube soft-crashes when going full screen sideways

Steps to reproduce : - go to YouTube - open a video - press the full screen button or tilt the phone sideways to trigger full screen - Firefox crashes and forces back to home screen - if opening Firefox again only half of the video component shows as in portrait mode, rest is black screen - if attempting to go side/full screen does properly show the video, but going back again to normal screen still shows the half black screen

I can reproduce this with a almost 100% rate, it only fixes itself by restarting Firefox, where it will work until phone is put to sleep mode.

I tried reinstalling Firefox from scratch, as well as deleting my browser cache and it didn't fix.

Firefox on my android phone times out on any webpage whenever I am not connected to a Wi-Fi. All webpages and IP addresses timeout with no response. Same issue occurs on Firefox Beta app and Firefox Nightly. All other applications work as expected with full internet access on mobile data. The same pages/addresses respond as expected on Chrome and the built-in browser.

Simply put, all Firefox apps have no internet connectivity on mobile data.

Solutions I've attempted with no success or change: Re-install Firefox. Logging out of Firefox Sync. Clear Firefox data and cache. Disabling tracking protection. Disabling HTTPS-only mode. No proxy settings are enabled. Confirmed Firefox application has mobile data network privileges. Disabling, re-enabling mobile data network privs. Installing Firefox Beta and Firefox Nightly; same issue.

Another possibly related issue: Firefox does not follow routes from a Cisco AnyConnect VPN on my phone. Opening pages/IP addresses routed through the VPN are rejected or timeout as if the VPN is not active at all. The same pages/addresses respond as expected on Chrome and the built-in browser. This occurs over Wi-Fi as well, of course nothing works on mobile data as described above.

Device: Oneplus 8T (KB2003) OS: OxygenOS 13.1 (Android 13) Firefox version: 117.0.1

This is the error message received when attempting to connect to provider to download emails. Have several accounts but only happens on one account.

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I've seen this error msg before but have no idea why it stopped.

This time it doesn't stop.

Have no idea how to fix this ***Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.***

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

I have no idea what is happening... But after restarting, clearing my cache, making sure I have data and it is working for other apps... Still no results.

No matter what, whether I try to type in a URL, click on a link in the google app, or refresh a page I already have open, the app doesn't even attempt to load a page or throw up an error. Just a blank background, no loading bar, no error messages, and no redirects...

This is driving me insane. On mobile data (3,4,5g) Firefox will not open any websites, it just sits with a white page until eventually I get "connection reset". Every other browser on the device works fine though, and Firefox can access sites when on WiFi.

I have uninstalled and reinstalled the main app *and* installed focus,beta and nightly versions,all have the same problems. Permissions on mobile data are allowed.

I cannot even get a sensible log or network trace out of the browser as there are no Dev tools.

It sometimes feels like Mozilla are trying their absolute hardest to lose users, I even had had the old "browser uses 12gb of memory for two tabs" problem on desktop the other week.

I was able to send emails till July 14. After that day it's been impossible to send or reply to messages from my Outlook account (I receive emails though). I have made no changes to Thunderbird's configuration since then. Basically it's the Oauth2 authentication that fails. I briefly see a browser page for authentication, wait, wait, wait and then the mail is not sent and I get an error message related to servers timeout (attached). Sorry, my interface is in Italian, but anyway the message is something like: "Unable to send email because of a timeout on the connection to the out server (SMTP) smtp.office365.com. Try again." Is this a known bug? Any ideas? It's quite annoying to use the browser interface to send messages while I am able to receive them in Thunderbird :) Thank you in advance, guys!

In the Profiles directory, under the correct folder for my account, I have a file called inbox which seems to contain all my emails. Unfortunately, that email is 4.9 Gb in size! I have moved a whole bunch of emails (several thousand) out of my inbox into an subfolder of Archives and then compacted the inbox folder, but seems to have made no difference at all. So, how do I decrease the size of that inbox file? I just downloaded the latest TB 115 onto my Windows 10 laptop. Thanks Noel

I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.

Since installing Supernova, I find a huge (multiple minute) delay whenever I open a folder to a new tab or window. There was zero delay on the prior version to open a folder, so it appears to be specific to Supernova. I'm surprised that no one else has mentioned it on the forums yet, so it seems it might just be something about my particular setup. Can anyone help me diagnose what I might be doing wrong?

Over the last two days (starting just before the latest Thunderbird update) Thunderbird is crashing 3 or 4 times a day, and is intermittently failing to download emails. Opening attachments (e.g. PDFs) to emails can take several minutes, whereas previously it was almost instantaneous. Task Manager shows that Thunderbird's power usage is 'very high'. None of these problems has happened before. I'm running Windows 10 on a PC.
