What Prevents Twitter Gifs from Playing on Firefox

After going through some fixes and solutions, we concluded that the following are some of the most important reasons due to which this error occurs.

• Internet Hiccup: It is possible that your internet service is facing degradation due to which you are running into the twitter gifs not playing issue on Firefox. Therefore, we recommend that you try and perform a clean start on your Internet Router which can often fix this issue because some DNS cache and launch configurations are cleared whenever the router is restarted.
• Corrupted Cache: Sometimes, the cache that your internet router has built up needs to be cleared because it has been corrupted and is thus causing issues with Twitter videos and gifs not playing. This cache is automatically regenerated so you do not need to worry about any data being lost.
• Add-Ons: In some cases, the add-ons that the browser has configured might be preventing Twitter gifs from playing on Firefox. Therefore, in order to fix the Twitter gifs not playing Firefox issue, we recommend that you disable add-ons by booting in the safe mode as indicated below and check to see if the issue is fixed.
• Hardware Acceleration: If the hardware acceleration feature on your browser has been enabled, it can sometimes be fruitful to disable it because if your browser might not be playing well with your hardware and driver configuration which is spurring this issue.
• Firewall Issue: If the computer’s firewall is preventing your browser from being able to load the Twitter website properly from their servers, the Twitter gifs not playing error might be triggered. Therefore, we recommend that you whitelist the browser in the Firewall so that all connections are whitelisted for Firefox.
• Disabled Flash: Sometimes, you might’ve disabled the Flashplayer on your browser which is sometimes required to load certain content properly. Therefore, it is recommended that you enable it and then check to see if you are able to fix the issue.
• Adblock: Software such as Adblocks often block certain content from websites which prevents ads from being loaded. Therefore, it is possible that your Adblock software is preventing Gifs from being loaded on your computer. Therefore, it is recommended that you try and disable the software for a while and then check to see if the issue is fixed.
