I want to see/manage some added extensions on Firefox on my PC (Windows 7), but after clicking the menu button and add-ons icon appears a blank tab (about:blank), so I not only can't select Extensions manager, bur can't see anything there. Failed also to open Extensions & Themes from Menu - Options (about:preferences). Please advise how to proceed. Thank you.

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

Hi

What happens when you go to open the add-ons option from the menu in Firefox? Is there any error message displayed?

有幫助嗎?

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Hi,

Thank you for responding.

@ Seburo - no there is no error or any other message. Just when I click the menu button and add-ons icon a black tab appears. I have noticed a couple of times that a tab with extensions tries to appear, but it very quickly changes to a blank one. I can hardly notice it. Thank you!

@FredMcD - it worked! Thank you!
