New tabs vanish when I view another one, MOST URL's vanish after a second and that is a safety issue if you can see if you are on the right page!

A while ( couple weeks ) before the last update and change I noticed my URL's were vanishing a second after I arrived on a page. Not all URL's but most. This is a safety issue if I can't see I'm on the right page and have not been diverted. ALSO, I can't copy them to send a link via email if they aren't there! I found a way in the old FF click down list, but even that feature is gone on this new version! This needs fixed at once.

AND when I make a new tab it vanishes! Or worse does not display like a tab. I can't go back and forth between pages if the tab vanishes. This started with the last FF update and change. This is poor design!!! When I updated the restore previous session grayed out. All my tabs were gone and I don't have them all in history. I was researching some things and it was important, now I can't remember them all. This is not a good thing! Unless you pin all your tabs immediately they will vanish??????? Stupid design. It does not even show the new tab for THIS page!!! "but is does show your URL....hmmmmm" What is the reason for having an arrow go through open tabs if they vanish??? PLEASE FIX THIS or I'll have to change browsers, I'll have no choice. How can you do anything if FF erases your URL's or tabs!

Hey Fox1User, Thank you for your message. I believe that this will happen when you have a dark theme applied to the new version of Firefox. It has been resolved in the 29.0.1 update that went out yesterday and would love to hear if this has improved the issue for you. I understand that the tabs are disappearing and it sounds like they may be blending into the tab bar.

However! if this is not the case, can you please show a screenshot of the tabs How do I create a screenshot of my problem? after trying to produce this in Safe Mode Diagnose Firefox issues using Troubleshoot Mode.

I hope we find the culprit, looking forward to your reply.

I also noticed you have 4 versions of Flash installed.
