When watching a video, if you set it to 720p, sometimes the video resolution is automatically reduced to 480p or 360p. Occasionally, it seemed to me that the resolution, on the contrary, increased to 1080p. I tried turning hardware acceleration on and off, it had no effect. This does not happen in other browsers.

Hi All,

Sorry to bring up legacy apps but I am trying to configure legacy portable versions of Firefox v3.6.28, v10, v20, v30 to run on portable version of Java - this is due to the URL/App being access only support Java 6/7 BUT on the Windows OS there is local install of Java 8 that the URL/App will not support.

Following this post which https://portableapps.com/node/21946 from the guide provided from user Kulmegil

I tried scanning my Firefox Portable along with other files with an up-to-date Clamwin:
K:\FirefoxPortable124\App\Firefox64\notificationserver.dll: Win.Virus.Zard-10023240-0 FOUND

That's not what I hoped to hear. I checked the PA site's info on virus reporting:

Hey
Sorry if this is a repost.
What's the best way to register a portable app lets say Firefox on Windows 11 as a Standard browser?

Update: When making FF as a Standard browser in the app itself I am able to add it in the win 11 standard apps panel.
Unfortunately it opens now with the clean default FF profile. Any solutions for that?

Hello,
I am using Firefox Portable version on my desktop computer. I want to copy the "FirefoxPortable" folder (extracted from the installer) to either another location on the same computer or another computer or usb drive.

And which files are not needed for normal run?
eg.? Data\profile\datareporting\archived

The last known working version is 117.0.x...

Hopefully there's a work around, otherwise I will revert back to 117.

I've just tried out Firefox 115.4.0 legacy...When I try to start it on my Win 7 system, I get an error message stating 'Firefox 116 and later require Win 10.....run Firefox legacy 115 instead'

When I press yes, it produces the same message.
I have had to go into the Firefox64 directory to start Firefox from where it starts normally.

Also, I have downloaded the legacy and the ESR version of Firefox, As I'm using the legacy version, do I need the ESR version?

Thanks.

Hello:

When I click on Help and then About Firefox I see the message 'Checking for updates' and then I get 'Failed to check for updates'

I have manually installed FF 115.3.1 and know 115.4.0 is available. Using Win10 and FireFox is on a portable USB stick
