Interesting error message in FF/Windows 10

[mbms 5]

Recently I got an error message in Firefox that a Skitch related Javascript stopped working. Now I wonder why I get this one, though I did not use Skitch for a long time, and the addon is not even installed? Could it mean the Web Clipper, while it writes "Skitch"?

Hi.  I've never seen that error,  though Skitch is still installed on my system.  Does the error prevent you doing anything?

It did not prevent me doing anything - I just had to kill  Firefox with the task manager to be able to use my computer again. 

I didn't use Firefox for a long time, but intended to use it again. So, I installed it again (fresh), installed web clipper, ublock, noscript, and my favorite bookmarking addon (diigo, which I used for years already). Within the first week I felt so stressed by a really really slow web experience that I decided to go back to a Chrome based browser (Iron browser) today. :-)

Edit: I must say, I was surprised, that FF still knew my old bookmarks,... though it was not installed on my computer for almost a year. I decided to install it again, because I really missed some good equivalent to noscript in Chrome.

Long time ago I had Skitch installed, but it does not appear under "addons" now, and in the meanwhile I uninstalled and installed Firefox multiple times. That's why I felt confused why FF complains a JS file with Skitch in its name stopped responding. I cannot reproduce this behavior for now.

Hmmn.  Firefox is not the most stable of browsers,  and it's a memory hog on my system,  but it does the job - usually - though I get the odd crash.  I'd ignore the problem unless and until it starts to recur...
