Some buttons disappeared from my server panel, everything is working when entering from some other device.

Even on codeberg I could't send the issue, because of javascript errors, had to do it through mobile:

Did you update from 147.0.3-2 to 147.0.4-1?

Try starting LibreWolf in Troubleshoot Mode with the button Open and see if that fixes deepseek or your missing buttons.

@any1here I don't remember which version it was, sorry.
Troubleshoot mode didn't solve it :/

Overwriting portable files with the latest also didn't work out.

Where are you getting the portable version from?

In LibreWolf-WinUpdater.ini, you can find LastUpdateFrom and LastUpdateTo (unless you're using the PortableApps.com release, which is not supported).

Rolling back to 147.0.3.2, by overwriting files didn't help :/

Extraordinary, when I try to start 147.0.3-2 from clean portable file, it works. Still don't understand what could be the reason, disabled all extensions, went to troubleshoot mode, no reaction.

So if you download the latest version and copy over you Profiles folder to that new download, it doesn't work either?

It worked! Though I don't know if for too long.

If you still have the old non-working LibreWolf folder (which is next to the Profiles folder), compare it to the newly downloaded (working) folder - e.g. with WinMerge or Double Commander - to see if any of the files differ/are missing.

Perhaps one of the files wasn't replaced with the new version, which either happens if LibreWolf was still running during the update (but that's basically impossible with the measures in place) or possibly if some antivirus software blocks access to the file.
