Thank you for ForecastFox (Fix). It's the best thing going if you want/need a weather extension for Firefox!
However, since the update to Firefox Quantum (Firefox 57), I have noticed a problem. This problem mostly appears when viewing a document in Google Docs/Drive. I've attached a screenshot. This problem forces my computer to slow WAY down, as the swap file takes over the monstrous task that is imposed. Firefox 57 reports that a script associated with ForecastFox (Fix) is slowing the system down. This situation essentially locks my system up for up to 20 minutes at a time. In the interim, I've taken to disabling ForecastFox (Fix) whenever I use Google Docs/Drive.
My system is runnning PCLinuxOS, and Firefox is updated to the latest version.
Thanks for the extension, and thanks for taking a look at this issue!
