That is Firefox's interpretation of "caret browsing" press "F7" to turn it off. It is a toggle and the toggle may or may not provide a warning message when turning it on, it never provides a message when turning it off. If you see the message, reply "No" to turning on caret browsing.

Keyboard shortcuts and certainly not for dedicated keys have not been changed.

• Firefox and other Browser Keyboard Shortcuts (Comparison Table)

thanks for your time, surely, but problem not solved yet. 1) i used config settings as in your link 2) i do press F7 and then 'no' 3) scrolling up and down via cursor keys works, end/home works but scrollling via pgup/pgdn keys doesn't work, it simply equivalent to Back/Forward for current tab.

btw in your link for FF shortcuts info is out of date, for FF there is simply no combination mentioned such as ctrl+pgup/pgdn at all. this is simply not true - see what this combination do in your FF.

huhuh too sophisticated FF and again - how do developers decide if to change keyboard shortcuts or not? do you have any insights? or thisi is in essence the problem - no dedicated and genius product manager with veto right? =)(

ctrl+pgup/pgdn doesnt switch tabs as well, simply no any reaction

sorry, i didn't formulate clearly:

in a table there are combinations Ctrl+pgdn and pgup, but actually they dont work in my FF. and I made changes in about:config as you suggested in your link and I press F7 then choose No etc.

Combination: Ctrl+PgDn; Claimed function: Tab Next (on Right); Real action at my PC: nothing (if this is last page opened).

Combination: Ctrl+PgUp; Claimed function: Tab Next (on Left); Real action at my PC: go to previous page.

That part of that Keyboard Shortcuts table is a bit out of date.

{Ctrl + PageUp} and Ctrl + PagedDown} last worked for navigating thru opened Tabs in the Firefox 3.6 versions. Those keyboard commands quit working in Firefox 4 (and subsequent versions) when the tab strip was changed.

I believe that there is another way to indirectly navigate tabs on the 4+ versions, but at this time I don't recall what it is.

Make sure that you do not have NumLock turned on (Bios setting may reverse what is on or off, but with the light off for me it should not enter numbers on dual purpose keys)

The alternative is the only one I use Ctrl+TAB and Ctrl+Shift+TAB, but I have no problem with either.

If it is tied into to Tab Scrolling for that, as Ed mentioned, I do not allow tabs to scroll so that would not affect me.

• Tabs Bar Minimal Size - Themes and Skins for Browser - userstyles.org

I see now that switching tabs with Ctrl+PageUp and Ctrl+PageDn not only is what the original poster was talking about but that he knew about use of the Ctrl+Tab alternative. I really would suggest getting used to using the Ctrl+Tab and Ctrl+Shift+Tab as the other is affected by the NumLock key.

Also turn on toggle keys so that you do get an audible warning when Caps Lock or Num Lock is invoked. see item #9 on

well, guys, sorry for delayed answer!

i do really appreciate your advice and i tried everything you said but it is tooocomplicated for me, so last few days i returned back to Chrome which has absolutely no problem. i guess large google may have some product management best practice developed from hundreds of product management exercises, and for FF team it is in some way one of more importance and hidden agendas/preferences, so FF team doesnt really understand that keyboard changes are not the same with any kind of design/menu changes. so - unfortunately - i need to save precious time and use chrome. i will check future FF versions and hope for the best.

by the way how does FF team conduct feedback on such things as i raised in this thread?

You may have switched on caret browsing.

• http://kb.mozillazine.org/accessibility.browsewithcaret

You can press press F7 (on Mac: fn + F7) to toggle caret browsing on/off.

• Tools > Options > Advanced : General: Accessibility: [ ] "Always use the cursor keys to navigate within pages"

• http://kb.mozillazine.org/Scrolling_with_arrow_keys_no_longer_works
• http://kb.mozillazine.org/Accessibility_features_of_Firefox

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Hi,

thanks for help, but I already played all games with this caret browsing etc.

Really - FF simply decided to leave some keyboard shortcuts (with no rational reason or optionality to return back old keyboard shortcuts), while Chrome allows to use ctrl+tab and older ctrl+pgup/pgdn.

I will hope that someday I will have an opportunity to return back to FF from Chrome.

And, again - nobody answered me how those decisions are done among FF developers. Because, again, at google there is a function of product manager, who cares about user experience (doing A/B check for example etc.). =)

Again, thanks for your support!
