Hi There, Please see the attached image. As you can see there are no menus to select in the top menu bar. When i scroll through they drop down but show nothing or partial info.

Can you help? Is this a software or hardwear issue? I do not have this problem with any other software on my mac.

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 FredMcD,

Many Thanks for your post and advice. This has solved the problem.

Please let me know next steps? I obviously have extention/add-on issues, right?

Cheers Richard.

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 FredMcD,

The hardware acceleration turn off seems to have done the trick.

Thanks for your help.
