Firefox is not allowing me to interact with certain elements on webpages. Here is a list of some of the websites that I have trouble with:

- and

 I can't use the video controls


 I can't use the seekbar.


 The arrows of the price range slider don't drag. Instead, the underlying text is selected.

I tried using Firefox on a friend's Mac and it's working properly. I guess it's a problem with an entry in my about:config, but I don't even know what to search for to describe this problem.

I'm using Firefox 33.1.1 on Mac OS X 10.10.1 (14B25).

Chosen solution

Setting dom.w3c_touch_events.enabled to 0 in about:config solved it.

Many site issues can be caused by corrupt cookies or cache.

If there is still a problem, Start Firefox in Safe Mode {web link} While you are in safe mode;

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Then restart.

Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default

You may have a corrupt cookies.sqlite file.

Type about:support in the address bar and press enter.

Under the page logo on the left side you will see Application Basics. Under this find Profile Folder. To it’s right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Locate the file. Then rename or delete it. Restart Firefox.

Thanks FredMcD for your reply.

Renaming the prefs.js file to prefs-old.js seems to solve the problem, which proves that an entry in my about:config is what's causing it.

Is there a way I can just remove the individual entry/entries causing this? I don't want to lose all my configurations.

What you would have to do is print out the old prefs.js file, and compair it to a clean copy. As to what to check . . . . . .

BTW; this can be opened in a Word program. BUT make no changes unless you know what is going on.

Can you attach a screenshot?

  • Use a compressed image type like PNG or JPG to save the screenshot
  • Make sure that you do not exceed the maximum size of 1 MB

Make sure that you allow pages to choose their own colors.

  • Firefox > Preferences > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"

Note that these settings affect background images.
