Firefox Support Forum

I get the following message when going online with Firefox: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I've followed all the prompts to restart the computer, refresh the computer, delete the favicons.sqlite and places.sqlite and it won't allow me to delete them. This happened yesterday as well. Yesterday I could delete those files and everything was restored. But today I can't get it to work.

I start Firefox from a batch file (Win7) on the first boot of the day. Manually I choose my "NEWS" bookmarks folder, then slide down to "Open all in tabs". (attached image) (Then I go pour a coffee while the news article tabs open and load data!)

Please and thank you, is there a way to specify this action from the command line? And if so, what is it?

I believe that I could use such a mechanism in other ways, such as opening all tabs in my "Forums" folder of bookmarks, or on Mondays, opening all tabs in my "Weekly" bookmarks folder.

Thank You, Chris

I recently upgraded from Window 7 to windows 10. Ever since, the spacing between the bookmarks has significantly increased. I read several post about this and they all seem to be looking for something in Firefox. I think it has to do with something in windows 10, not Firefox. Any ideas? I've already done the Density/Compact thing. Slight improvement, but not anything like it was under Window 7.
