I always interrupt work by some 5-10 minutes: household keeping... or even longer for preparing food, eating, being out, ...

I designed these instead of using bookmarks, because I added additional description text as well as specific icons, grafics and many other information. 'startseite' contains all links to sub-pages or direct page links, wihle subpage '_Zeitungen' contains only links to newspapers, of which I read a few every day, some only once per week, other only occasionally.

(9) Summary:

For me I can see somehow a relation to bookmarks,

However, before I switched off the message, it was alwas related to the message "plugin container not working"!

So?

I wonder, why FF does not respond, when in WIN-Task manager it is marked with "inactive", having a CPU-load of 25%! If I would have programmed my software for automatation in chemical plants or refineries, they all would have been blown up to pieces.

-(

Did FF development consider and investigat in a possible problem in the communication to the windows operating system/ressources, thus an issue not related to FF? Can we exclude this?

Thank you so much for your attention

You keep quite a few bookmarks and history items with places.sqlite being over 100 MB in size.

Table moz_places has 151804 records
Table moz_bookmarks has 166062 records

Firefox needs to check the places database in a lot of cases to possibly update a visit count or to provide suggestions when you type in the location/address bar. You can expect performance lost with that many items.

To the OP, I had a similar problem outlined here, for 7 months: https://support.mozilla.org/en-US/questions/1068669 (it's been archived)

Every time I was moving a bookmark, or sometimes even saving/deleting ones, the Library would hang and CPU usage would go to 50% for 20 seconds.

Just tonight I found the cause, and therefore the solution (albeit not perfect): click on Menu, go to Syncing and UNSYNC bookmarks. So for me at least, Syncing was causing the freezing.

Yes I admit I have thousands of bookmarks, my places.sqlite is about 30 MB. That is the issue.

I manually back up bookmarks every day, so for me that's not a big issue. You'll have to remember to do that and also maybe turn on Syncing once a week.

Moderators please update topic.
