I greatly appreciate any help you can provide in getting the "ThumbsDown" add-on to work on my imac. I am using "thumbsdown-0.22.2-3.xpi" with Firefox 33.0. I would like to go to a site like "http://hqcelebrity.org/thumbnails.php?album=302" where thumbnails are shown, get the links to the high resolution pictures and batch download them all. ( I can batch download the thumbnail pictures with "DownThemAll" or with "Outwit"), but not the high resolution pictures.

I tried installing "DownThemAll" but it seems to be greyed out in the Tools menu, and there is no icon at or near the location of the successfully installed "DownThemAll" icon. Your help and advice is greatly appreciated. Also, If you know an alternative to "ThumbsDown", please advise.

Thanks kindly for your help, Sincerely, Bradley Katz

Hello,

The ThumbsDown add-on appears to have last been updated over a year ago. You may want to email the developer to ask that they update so that it is compatible with the latest version of Firefox. Please see the articles Unable to install add-ons (extensions or themes) and maybe Re-enable add-ons that were disabled when updating Firefox.


If you are sure that you want to install the add-on regardless of potential issues, you can install this extension:

I am not entirely sure how it works, but it sounds like you may need to go to your about:config page to change the extensions.checkCompatibility preference to false once it is installed. You might then be able to enable your ThumbsDown extension.

Note: you may want to back up your profile first, please see the article Back up and restore information in Firefox profiles for more information.


In order to change your Firefox Configuration please do the following steps :

  1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
  2. Click I'll be careful, I promise! to continue to the about:config page.

Thanks for your response, but I still can't get ThumbsDown to work. Can you suggest an alternative add-on for Firefox or an alternative program for the mac?

Thanks a lot for your help Sincerely, Bradley Katz

Sorry, I don't use anything like it and am not sure what applications are available for macs that have similar functions.

If you go to the about:addons page, or:

  • Edit (or New Fx Menu) > Preferences > Extensions

You can click on the gear beside the search in the page, and update all add-ons. If DownThemAll is giving you problems, maybe that is the only thing that needs to be updated. You can also use that search bar to try to find what you are looking for.

Good luck!
