Greetings, Windows 10, latest version, recent uninstall then re-install. When I load Firefox and populate several tabs, Windows Task Manager shows that the "Mem" column (2nd in "Processes" tab) slowly lists increasing memory, up to over 1200 MB, at which point there are hangups, "not responding," and finally seizure or crash. I tried the "about:crashes" route, and will try again if you want. In contrast, I can have over 50 tabs open on Google Chrome and memory usage peaks at less than 200 MB. I'm using Chrome now, but will gladly communicate using Firefox if you want.

We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

The crash report is several pages of data. We need the report numbers to see the whole report.

  1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
  2. Copy the 5 most recent Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)
