This morning I noticed that there were some weird things happening in Firefox and pages were crashing all over the place including my wordpress editor, my umami console and various other pages. I had some weirdness with Gnome and Ubuntu on my laptop this morning so I thought it was operating system instability.

Then, I came across someone on Lemmy who was experiencing similar problems and blamed the Proton Pass plugin. The error messages I was getting in the console didn't mention proton but they were similar in nature. I disabled the addon and hey presto, I got some stability back on my system.

If you are having this problem and you're a proton pass user, you will be pleased to know that Proton are working on getting it fixed but in the mean time you can go to the official addon page and download v1.14.1 to forcibly revert your plugin and restore stability until the new version is out.
