This release changes the function of the 'wheel' on a mouse.

Instead of scrolling up & down a page, it now 'zooms' in and out.

Is this deliberate? Or, is it a bug?

Microsoft USB Basic Optical Mouse v2.0

Since the last but two update. actually in January. this is what has happened to the message boxes on MSN. That is someone replies to me through a comment and a box with the reply pops up. This is the result.

I recorded USB webcam pictures with MJPG_streamer and converted them to mp4 using

  ffmeg -r 20 -pattern_type glob -i "*.jpg" -c:v libx264 test.mp4

Firefox complains "video can't be played because the file is corrupt" Google Chrome and VLC have no problems playing the file.

What options for ffmpeg do I need to create the mp4 files so that firefox can play them?

The firefox web console says: could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004) Details: RefPtr<MediaDataDecoder::DecodePromise> __cdecl mozilla::WMFMediaDataDecoder::ProcessError(HRESULT, const char *): MFTManager::Output(2):80004005

Since the update a few days ago, Firefox is crashing and some sites such as Trust Pilot, do not work at all on Firefox. I know it is Firefox because it works fine with Chrome. Even Google Search does not work right.

What is the problem?

Hi - Firefox has been randomly crashing a lot lately for me. Here are the report numbers - bp-d13cc7f7-782b-4308-a209-751540230320 bp-c3c23d0b-0e10-44cd-aa24-9f86f0230320 bp-4206a498-bc21-45d4-91b8-2edb40230320 bp-230d21d1-0527-4806-9da1-9aa8b0230320

Hi,

im getting unknown issuer on my thin-clients with a FF ESR 45.9.0. This FF is tied to the OS (Ubuntu 16.04) and the OS is the most recent compatible version for our version of the thin-clients. So yeah its super old and I'm not able to update any of this. There is no security.enterprise_roots.enabled option available. What would be the best way to solve this issue for ~400 clients. Thanks in Advance Regards Tekkion

I'm not sure how this happened but now having a hard time reading text because the background is so bright. I went to settings but was unable to find any way to change the brightness or at least a darker background cover. Please help.

Im trying to uninstall fire fox cause i prefer another browser but when i press uninstall it doesn't to anything and i tried to search up the problem but nothing pops up

The interface fonts in my firefox are impossibly tiny

Specifically where it is an issue is when I go to bookmark a page - the menu interface is in TINY font and despite totally resetting firefox and creating a brand new profile etc etc

I have NOT been able to change it - I am at my wits end

I attach a screen shot to show you It also happens on the firefox home screen with frequently visited sites

PLEASE help me

Lily

I have over 800 emails in my trash folder. Do they delete automatically every month? If not, how do I empty the folder? Also, when I take a screenshot of something, how do I email the screenshot?

Thank you very much!
