Hello! I understand that you're experiencing issues with pdfFiller losing connection or crashing. Let’s troubleshoot this together!

First, I’d like to gather more details to better understand the situation:

1. When did this issue start happening? Was it after a specific update or change to your system?
2. Are there any specific actions you take that lead to the connection loss or crash, such as uploading a document or using a particular feature?
3. Are you using the web version of pdfFiller, or are you working with a desktop application?

Once I have a bit more context, I can suggest some targeted solutions!

pdffiller started crashing about a month ago. I am using the web version.

Thank you for the additional information! Since the crashing started about a month ago while using the web version of pdfFiller, let’s start by checking a few things that could potentially resolve the issue.

### Step 1: Clear Your Browser Cache
Clearing the cache can help resolve many issues related to web applications.

1. Open your browser settings. (For WebKit, you can usually find this in the top menu.)
2. Look for the option to clear browsing data.
3. Select "Cached images and files" (you can leave cookies unchecked if you prefer).
4. Click "Clear data."

### Step 2: Disable Browser Extensions
Sometimes, browser extensions can interfere with applications.

1. Go to your browser extensions.
2. Temporarily disable any extensions.
3. Reopen pdfFiller and check if the issue persists.

### Step 3: Try Another Browser
If possible, test pdfFiller in another browser to see if it crashes again. This can help pinpoint if the issue is browser-specific.

### Step 4: Update Your Browser
Make sure your browser is up to date:

1. Go to the browser's settings.
2. Look for an "About" section to check for updates.
3. If an update is available, install it and restart your browser.

### Step 5: Check for Internet Connection Issues
Ensure that your internet connection is stable. If your connection drops or is slow, it might cause pdfFiller to lose connection.

1. Try restarting your router or modem.
2. If possible, connect to another network to see if the issue occurs there as well.

If the problem still exists after trying these steps, please let me know. I can look for more specific information regarding potential compatibility issues or further troubleshooting steps. Are you satisfied with the solutions I provided?
