Tested in FF 43.0.4 on Ubuntu 14.04 LTS and Win7 and works as expected in both environments. Used mouse and then keyboard (tab, tab+shift) to focus on editor body, in all cases works as expected.

Can you provide more information about operating system and maybe there are some add-ons installed in FF?

@k.krzton Please read defect summary & description before commenting. I'm talking about issues with TAB key Navigation in toolbar groups(Notfocusing in & out of editor body) I clearly mentioned what's expected & what's actually happening. Once you navigated to first group in Toolbar by pressing ALT + F10 from editor body & subsequent TAB key press should navigate between toolbar groups. Focus should not come out of editor toolbar. Focus should go to editor body onely when user press ESC. Please see IE/CHROME for correct behaviour.

I didn't make my description clear enough, sorry for that. What I meant here:

refers only to point:

2. Navigate to editor body

which means I tried different methods for navigating to editor body. Apart from that all steps where reproduced same as you described and I still was not able to reproduce the issue. This means that after focusing in first group in Toolbar by pressing ALT + F10, subsequent TAB key press navigates between toolbar groups and focus goes to editor only after pressing ESC. I also compared this behavior with Chrome and it is same in both browsers.

I did not close the issue so it can be investigate further. Providing additional information which I asked earlier could be helpful.

I was able to confirm this issue even in CKEditor 3.x so this looks like Firefox regression.

I'm using Win 7 and FF 43.0.4.

@j.swiderski Thanks for confirming it. yes it definitely is a Firefox regression, But we need to confirm it & if you think it's firefox defect it has to be logged with firefox or CK has to fix it if firefox changed something recently.

I can't repro it with the exact same setup as @j.swiderski so I went with checking on multiple combinations and tested three different setups:

• Win7 + FF 43.0.4 - can't repro
• Win7 + FF 47.0a1 (nightly version) - can't repro
• Win8.1 + FF 43.0.4 - can't repro

All combinations were tested on ​mentioned nightly build.

@satya @j.swiderski Is there a chance that you guys have some extensions or anything else affecting FF?

[Jakub Ś]

I have just the Firebug.

One note - I have cleared cache (Ctrl+F5 has given me same result) and with every new Alt+F10 Tab I could go to one group further until I could reach all of them. Really weird.

[Jakub Ś]

After some testing I have discovered that this issue is happening only when Firebug is opened.

When tabbing with Firebug closed or even with native Firefox WWW console (Ctrl+Shift+K) everything works as expected (it was enough for me to refresh page with Ctrl+F5 before every setup). It looks like Firebug is breaking the Tab order.

@satya could you recheck and let me know your results?

@j.swiderski This issue is not happening when i de-activate firebug, so we can close it as firbug issue.

Thanks for confirming that Satya!
