Why does my window appear blocky and pixelated when I resize the window?

Every single time I either resize the window or scroll through pages, firefox does this strange visual glitch. It doesn't happen on chrome, internet explorer, or anything else. I have already tried downloading and updating firefox to its newest version, but to no avail. I'd really like an answer to this, as it is horribly annoying. Thank you.

Chosen solution

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

Yes, this fixed problem @FredMcD. Must I always start Firefox in safe mode every time I want to get rid of this problem?

It could be the work of one of your add-ons. 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.
